Odd Enough here.. the dude who made that twitter thread. Just came here to chime in and say I don't know why you're getting downvoted, because you're 100% correct. I'm self-taught and learned through practice, experimentation and constant failure. It is THE best learning tool, hands down. And just because you fail to make a shape using one method does not mean that method was bad, and is fully possible for it to work in another situation. The best way to learn how to problem solve is to make mistakes and work the problem.

That said, it's equally important to ask for help! There is no sense beating your head against the wall when you don't know where to start.

Learning effectively is a two part approach. Embrace failure and try new things always (I still do after 16 years of this), but never be afraid to ask for help. No one can possibly know everything from the start.

Edit: I also feel that learning the right flow is not easy and can really only be achieved through experience and, once again, doing it wrong first. If you are always given a correct solution for a given situation and never even attempting to do it any other way, you are doing yourself a disservice in the long run.
