Seriously just sit down and dedicate a week to typing solely in vim. It feels extremely weird at first, and you'll keep wanting to use the arrow keys. But after that you'll never want to go back to using non-vim mode editing again.
But in all seriousness, sometimes people just need to pay money for something to feel committed to learning.
Also, some people dramatically prefer the format of a human talking to reading text. You also get insightful tangents, from listening to an expert give an intro, that are sometimes worth the price of admission themselves.
I personally love to watch high performing programmers work, you learn so much just from the nonverbal parts, get workflow inspiration, etc.
