Problems with "Fake It Till You Make It"

This is definetly pedantic, but also:

“Just genuinely try to build the small habits that move you closer to who you want to become.”

So are you saying you should extend yourself to try things you might not normally do? Things that may not be a part of your personality? Could this perhaps be described as being fake?

“it encourages people to present themselves as something they are not.”

If you are not comfortable with public speaking, it is ok to pretend you’re comfortable.
