It's always too early to quit.

Without hard work, nothing grows but weeds.

The dog that trots about finds a bone.

If you're going through hell, keep going.

To know oneself, one should assert oneself.

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

Be thine own palace, or the world's thy jail.

The secret of getting ahead is getting started.

Either you run the day or the day runs you.
