One should collect good resources(like resource for clean code, oops design pattern) of theory and go through it properly, and do hands on side by side.

I have seen people directly jumping into writing code by just taking help on syntax and they struggle later.

Certainly, here are three important things you should do:

1. Practice, practice, practice! Consistent practice is essential. It helps reinforce concepts. Solve coding challenges on platforms like LeetCode, HackerRank, or CodeSignal.

2. Build a strong foundation in data structures and algorithms. Invest in quality programming books and online courses. Structured learning can provide you with a strong foundation.

3. Apply what you learn. Build applications and solve problems.
