Know or listen to those who know.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

Either you run the day or the day runs you.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

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

If you're going through hell, keep going.

The dog that trots about finds a bone.
