The Simple Formula for Success

Learn theory → Build a small project → Push to GitHub → Share on LinkedIn 

Don't just learn passively. You have to practice. This means doing projects yourself, using the techniques you learn, so you experience first-hand how to do them. Make mistakes. Learn from the mistakes what works and what doesn't .
