To know oneself, one should assert oneself.

It's always too early to quit.

If you've got a talent, protect it.

Problems are not stop signs, they are guidelines.

Never complain and never explain.

The secret of getting ahead is getting started.

If you're going through hell, keep going.

The wise does at once what the fool does at last.

Do not weep do not wax indignant. Understand.
