To know oneself, one should assert oneself.

Either you run the day or the day runs you.

Without hard work, nothing grows but weeds.

It's always too early to quit.

The dog that trots about finds a bone.

Know or listen to those who know.

What you do today can improve all your tomorrows.

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

Things do not happen. Things are made to happen.
