This is a ridiculous thing to write a blog post about. The point of the saying is to mean "Try new things with fake confidence until you have attained enough mastery to have real confidence." As with life, the saying works great for some things, but not so great for other things. If you want to be a comedian, some times it's better to just go up on stage and pretend you've already mastered it, until you do eventually become a master. Self-doubt will kill you, so fake yourself out and just go for it until you're actually good. If you want to be a doctor, then obviously it doesn't work as well.
