Getting a teacher will without a doubt help with both of those things. Learning to play the piano is like trying to summit Mt. Everest while blindfolded. Technically speaking, you can do it alone but it's orders of magnitude easier with somebody guiding you. Sometimes all it takes is a nudge in the right direction. Other times they need to tell you specifically how to execute or understand an idea.

Definitely. Alas I’m not in a position to have that. Just yet, at least.

Nevertheless, in terms of optimization in the context of going it alone, having resources on _how_ to learn rather than _what_ to learn is great.
