How do I become the world's best programmer ever?
might as well ask how you become the best author in the world. Same question.
But I don't want to be the greatest author, I want to be greatest programmer!
Maybe this thread was too ambitious. How about just becoming a great programmer? How would a mediocre programmer could become much better?
idk. It depends on what field of programming you're trying to do. Also how you define programming. It's a really vague thing to want to be good at.
You'll be fortunate if you can count yourself as a 10X programmer.
