What I Learned From 100 Days of Code: Lessons From a Full-Stack Developer
As a full-stack developer with over a decade of experience, I‘ve learned that one of the most important things you can do for your career is to commit to continuous learning and skill development. But it can be challenging to make time for consistent practice amidst the demands of daily life and work. That‘s why when I first discovered the #100DaysOfCode challenge, I was eager to give it a try and see how it would impact my growth as a programmer.
The Power of Consistent Practice
The premise of #100DaysOfCode is simple but powerful: commit to coding for at least an hour every day for 100 consecutive days, sharing your progress publicly. What I love about this challenge is that it‘s not about reaching a specific skill level or building a portfolio-worthy project, but developing a consistent habit of daily practice.
Research has shown that consistent, deliberate practice is key to mastering any skill, and programming is no exception. A study by Dr. K. Anders Ericsson, a leading expert on expertise, found that elite performers across fields engage in an average of 3-5 hours of focused practice per day. While an hour a day may not turn you into an expert overnight, it‘s enough to start seeing significant improvements in your skills over time.
Personally, I noticed a huge difference in my ability to learn and retain new programming concepts thanks to the daily repetition and exposure. Consistency helped me overcome the "forgetting curve" and move new knowledge into my long-term memory more effectively.
The Motivation of Momentum
One of the hardest parts of any learning endeavor is simply getting started. But I found that once I committed to the #100DaysOfCode challenge and began logging my daily progress, motivation became much easier. The satisfaction of crossing off another day and watching my coding streak grow kept me coming back, even on days when I felt tired or busy.
Logging my hours each day also helped me stay accountable and honest with myself. It‘s easy to feel like we‘re making progress when we do a long coding session every once in a while, but tracking my time revealed that I was often overestimating how much I was truly practicing. Seeing the numbers in black and white was a wake-up call to stay focused and protect my coding time.
Some tactics that helped me maintain momentum during the challenge:
- Setting a consistent time each day for coding (for me, first thing in the morning worked best)
- Breaking my hour into smaller chunks (e.g. 2 x 30 min) when I was short on time
- Using an app like Toggl or RescueTime to automatically track my coding hours
- Bookending my coding sessions with a quick planning session and reflection
- Publicly sharing my daily progress on Twitter for extra accountability
Overcoming Obstacles and Plateaus
Of course, not every day of the challenge was smooth sailing. I definitely hit my share of obstacles, from getting stuck on a tricky bug for hours to feeling overwhelmed by how much I still had to learn. But #100DaysOfCode taught me to reframe these challenges as opportunities for growth, rather than signs that I wasn‘t cut out for programming.
One of the biggest lessons I learned was the importance of embracing a growth mindset, a concept pioneered by Stanford psychologist Carol Dweck. Dweck‘s research has shown that individuals who believe their skills can be developed through hard work and dedication (a "growth mindset") tend to achieve more than those who believe their abilities are fixed and innate.
When the going got tough during my #100DaysOfCode challenge, I had to constantly remind myself that struggling didn‘t mean I was a bad programmer – it meant I was pushing myself beyond my comfort zone and expanding my skills. Instead of getting discouraged, I tried to get curious about what I could learn from each obstacle.
Some strategies that helped me overcome plateaus and maintain a growth mindset:
- Regularly reflecting on my progress and celebrating small wins
- Focusing on the process (consistent practice) vs. the end product
- Seeking out new challenges and stretch projects to avoid stagnation
- Embracing failure as a necessary part of the learning process
- Surrounding myself with growth-minded individuals in the coding community
"The most successful people see failure and setbacks as an indication that they should continue to strive for their goals with even greater determination." – Carol Dweck, Mindset
Another key lesson from my #100DaysOfCode experience was the power of deliberate practice. It‘s not enough to just put in your coding hours each day – you also need to be strategic about what and how you‘re practicing. This means setting specific, achievable goals for each session, working on projects that challenge you just beyond your current skill level, and actively reflecting on your process and looking for areas to improve.
Some examples of deliberate practice techniques I used:
- Solving coding challenges or katas to target specific skills
- Pair programming with a more advanced developer to learn new techniques
- Deconstructing and recreating features from my favorite websites or apps
- Doing code reviews on my own projects to identify areas for improvement
- Live-coding on Twitch or YouTube to get real-time feedback and accountability
By focusing on quality over quantity and getting outside my comfort zone regularly, I was able to accelerate my learning and avoid the plateaus that often come with "lazy" practice.
Becoming Part of a Coding Community
One thing I quickly realized during my #100DaysOfCode journey was that having a supportive community is invaluable for staying motivated and overcoming challenges. On days when I was struggling to start my coding session, seeing the tweets and GitHub commits from fellow challengers around the world gave me the push I needed to keep going.
Some of the ways I plugged into the coding community during my challenge:
- Joining the official #100DaysOfCode Slack group to connect with other participants
- Participating in Twitter chats like #CodeNewbie and #DevDiscuss
- Contributing to open source projects on GitHub and supporting fellow developers
- Attending local meetups and hackathons to meet programmers in my area
- Blogging about my experience and lessons learned
| Platform | Metric | Value |
|---|---|---|
| Tweets using #100DaysOfCode | 200+ | |
| GitHub | Contributions during challenge | 100+ |
| Dev.to | Blog posts written | 10 |
| Meetup.com | Events attended | 7 |
Not only did these connections keep me accountable, but I also learned a ton from the diverse perspectives and experiences of developers from all backgrounds and skill levels. I even ended up collaborating on a few side projects with developers I met through the challenge, which helped me level up my skills even further.
Developing Grit and Resilience
Perhaps the most valuable lesson I learned from #100DaysOfCode was the importance of grit and resilience in the face of obstacles. No matter how experienced or talented you are, you will inevitably face bugs, roadblocks, and moments of self-doubt as a programmer. The key is learning to push through these challenges and keep showing up, even when it‘s the last thing you feel like doing.
Research by psychologist Angela Duckworth has shown that grit, defined as "perseverance and passion for long-term goals," is one of the strongest predictors of success across a wide range of domains. In a study of West Point cadets, Duckworth found that grit was a better predictor of retention than either IQ or physical fitness.
Throughout my #100DaysOfCode challenge, there were plenty of moments when I felt like giving up or taking a break. But by committing to showing up each day, no matter what, I slowly built up the grit and resilience needed to push through tough times. I learned to reframe challenges as puzzles to be solved rather than barriers to my success.
Some techniques that helped me cultivate grit during the challenge:
- Setting a clear, compelling "why" for my coding practice to keep me motivated
- Breaking large, overwhelming tasks into smaller, manageable chunks
- Celebrating small wins and progress along the way
- Practicing self-compassion and treating myself like I would a good friend
- Surrounding myself with supportive, encouraging mentors and peers
"Grit is living life like it‘s a marathon, not a sprint." – Angela Duckworth, Grit
Continuing the Journey
Ultimately, completing my first #100DaysOfCode challenge wasn‘t an end in itself, but a launchpad for a lifelong journey of learning and growth as a developer. The challenge helped me build the habits, mindset, and skills needed to thrive in an ever-evolving field, but I know I still have a long way to go.
Since finishing my first round, I‘ve gone on to complete two more #100DaysOfCode cycles, each time setting new goals and stretching my skills in different areas like machine learning and mobile development. I‘ve also become more involved in the coding community, both online and offline, and have even started mentoring other aspiring developers.
Looking back, I can say without a doubt that participating in #100DaysOfCode was one of the best decisions I‘ve made for my development career. It not only accelerated my technical skills, but also taught me invaluable lessons about the power of consistency, deliberate practice, growth mindset, and community.
