exactly. But, imo, you should do that in one point. Only then you can learn from mistakes, and learning from mistakes is the best learning. At least for me. Same in real life. Many examples, here's one: I'm confident and careful with ultrasharp cutting tools. But only because I cut myself bad a couple of times: before that I was more reckless even though I thought I was doing ok. Also others telling me to be careful had no effect whatsoever.

In the sense of tools in the real world (like hammers, etc) which are fundamental and basic to the task, used by everybody in the profession, and have staying power.

Frameworks on the other hand, are just some code some random guy (or random community) put together. Some are just awfully coded, despite their popularity. They are frequently rewritten. And they get out of fashion every few years.

It's funny you mentioned hammers actually, the movie playing in my head when I was writing that post was of a neophyte hammering nails in all day, struggling to remove nails with some contraption, eventually deciding that there must be a better way to remove nails and inventing the hammer with nail extractor head.

And some artists even specialize in sketches and concept drawings.
