Discipline is doing within, while you do without.
The winners in life treat their body as if it were a magnificent spacecraft that gives them the finest transportation and endurance for their lives.
Your attitude is a choice you make.
Winning is all in the attitude!
Start edifying the flowers. Stop pointing out the weeds.
Live each day as if was your last, not in the future, not in the past. You may not get what you want, but, in the long run, you will get what you expect.
