Go for it now. The future is promised to no one.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
If you're going through hell, keep going.
To be a good loser is to learn how to win.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
Begin to be now what you will be hereafter.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
The whole business of marshaling one's energies becomes more and more important as one grows older.
