Go for it now. The future is promised to no one.
Do not weep do not wax indignant. Understand.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
To know oneself, one should assert oneself.
If you've got a talent, protect it.
Have convictions. Be friendly. Stick to your beliefs as they stick to theirs. Work as hard as they do.
My experience has been that work is almost the best way to pull oneself out of the depths.
