Do not weep do not wax indignant. Understand.

The secret of getting ahead is getting started.

Never complain and never explain.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

It's always too early to quit.

Know or listen to those who know.

Problems are not stop signs, they are guidelines.
