Volume guarantees success
Try and fail.
Try again and again.
Run till you feel the burst in your chest, the fire in your lungs and the heat in your soles. Punch till you draw blood.
Fall, get up and jump back into the ring.
Try in different ways.
The most important things, are effort and the belief in yourself. The conviction. The self motivation.
There is no world where you end up failing in the end. Believe everything is aligned, conspiratorial, for you. Hell, even probability is on your side!
You fail when you give up!
