The way I did it is by trying to solve more and more advanced problems with simpler tools/features, then looking at more advanced features and seeing where they could be applied to make the problem solving simpler. Rinse and repeat.
An easy example that I can remember is making arrays that dynamically expand. I started with the barebones malloc and worked out how to use std::vector (and other list types) in its place.
Understanding that concept is, what I believe, to be the foundation of learning programming.
I’m no pro whatsoever, but using this method really helps me pick up and learn new languages.
