Key Tips

Code every single day — consistency beats intensity

Build projects, not just tutorials

Use Git from day one

Don't try to learn everything — focus on one stack

Join a community (Discord, Twitter/X dev community)

After 30 Days

You won't be a senior developer. But you'll have the foundation to build real applications, contribute to teams, and keep learning. The first 30 days are the hardest — everything after gets easier.
