Be gentle to all and stern with yourself.

Well done is better than well said.

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

It's always too early to quit.

Know or listen to those who know.

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

The dog that trots about finds a bone.

If you're going through hell, keep going.

Do not weep do not wax indignant. Understand.
