Go for it now. The future is promised to no one.
If you think you can do it, you can.
It's always too early to quit.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Only the educated are free.
The wise does at once what the fool does at last.
Never complain and never explain.
If you're going through hell, keep going.
Limit to courage? There is no limit to courage.
