Go for it now. The future is promised to no one.
Problems are not stop signs, they are guidelines.
Be kind whenever possible. It is always possible.
Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
Know or listen to those who know.
Well done is better than well said.
It's always too early to quit.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
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.
