It's always too early to quit.

To know oneself, one should assert oneself.

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

The secret of getting ahead is getting started.

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

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

If you're going through hell, keep going.

Problems are not stop signs, they are guidelines.
