Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Always desire to learn something useful.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Well done is better than well said.
To be a good loser is to learn how to win.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
