Best quote I ever heard was when one guy started shouting in the gym: "Yeah! Say it to me! Say I ain't good enough to lift those dumbells! Say I can't do it! Coz EVERY TIME you say it ama show you over and over again THAT I CAN!
There will always be people saying you aint good enough
There will always be people saying that you'll never reach your dreams
But then there's you proving them wrong - demarcus cousins
The pain you feel today will be the strength you've gained tomorrow.
Suck it up now and you won't have to suck it in later
