Go for it now. The future is promised to no one.
Always desire to learn something useful.
Do not weep do not wax indignant. Understand.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Know or listen to those who know.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
As human beings we do change, grow, adapt, perhaps even learn and become wiser.
