It's always too early to quit.

The most effective way to do it, is to do it.

Without hard work, nothing grows but weeds.

Go for it now. The future is promised to no one.

To be a good loser is to learn how to win.

To know oneself, one should assert oneself.

Who seeks shall find.

If you're going through hell, keep going.

Well done is better than well said.
