Everyday is the first day of the rest of your life. Don't dwell on your past mistakes, nor judge others for theirs.
Bodybuilding is not an endurance sport. Stimulate growth with intensity, load and isolation. Then go home to grow.
People often forget that it is your own choice how you want to spend the rest of your life.
Work hard in silence, let your success make the noise!
Each workout is like a brick in a building, and every time you go in there and do a half-ass workout, you're not laying a brick down. Somebody else is.
