I've always said -
Through the personal training, the bootcamps, the yoga... If it ends, when it ends, I want to be able teach enough so you're able to do it all over again on your own or with your friends and family.
The #1 thing you need, is an insane level of commitment. That's why I post "When you want to succeed as bad you want to breathe," as often as I do.
I somehow had that mentality as a young guy, many years ago :) Andy has it. You might, i just don't you the way i know andy. Just a lights out, F this, it's happening and not a damn thing is going to stop me mindset.
Commit. Anything you want, anything you want to see happen, commit fully and it will happen.
