Read This: Rog Law
This dude is always a good read, but this one is a MUST read: http://www.roglawfitness.com/10-ways-to-rock-2012s-face-off/
#2 mentions The Flinch - I was about 1/3 through this before my computer throat-punched itself this morning. It was, thus far, very good stuff. Best takeaway (again, thus far) was "Set your old self on fire." Follow Rog's link to get it. It's free.
#10 addendum: I watched the movie about The Runaways this morning and learned that Joan Jett's debut album was rejected by 23 labels...and "I Love Rock and Roll" went on to sell 10 million copies.
Don't give up until the Grim Reaper forces you to quit. And even then? Kick that fucker in the balls and run.
