I'm not a fan of Mr. Hulse, or his work.
But I'll try to put any potential bias aside, and address the guru's ramblings directly...
Ninety percent of your mind is in your body (sans
brain, that is)...? Suuuure thing, dude.
Motivation comes from the body? Bullshit. Motivation, unless it just kinda happens to you (in which case, everything's cool, at least for now...), is actually a choice
. Not a feeling, nothing fleeting like that. Applied willpower, is all. "Motivation", as most people think of it, is a lie.
Essentially, if you're feeling "unmotivated", you need to sack up and make a better choice. Yes, it's that simple.
Well, that's my take on all that.
