> Learning from solutions is one of the best ways to learn.

Sometimes I feel like that's the only way to learn. There's no worse feeling than staring at a problem and having no idea where to start with no one to guide you.

The corollary is that I feel sometimes it becomes _memorizing_ instead of _problem solving_.

In a certain aspect, problem solving is recalling previous solutions you've done and applying various parts of them. But in another sense, just memorizing solutions doesn't necessarily help you apply them.
