You don't hate strength training; you hate your working environment. Go back and read this post from December; think back to that enthusiasm.
I actually laughed out loud at your "I'm going to go out and change the world" attitude. It's admirable, but it's like putting Leonardo Da Vinci in a fingerpainting class. You're exactly what commercial gyms expect: an enthusiastic young guy whom they can suck dry for a few months until he quits. You fell right into the trap, I'm sorry to say.
I'd say your life cycle in that business is up; get out NOW.
The secret to success in this industry is finding people who aren't trying to do things better; they need to be looking to do things differently. You can't make something that is inherently corrupt and flat-out shitty "better."
Alwyn Cosgrove, Joe DeFranco, Jason Ferruggia, and several others have done things differently, and they love their jobs and are outrageously successful. We're doing things differently in the facility we'll be opening in less than a month, and there is no doubt we'll be successful, too.
Get out, take a break, rediscover your passion, and then seek out something that feels RIGHT - not "better."
I wish someone had given me this advice five years ago.
