To know oneself, one should assert oneself.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
If you're going through hell, keep going.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
Never complain and never explain.
To be a good loser is to learn how to win.
Preconceived notions are the locks on the door to wisdom.
