It's always too early to quit.

Do not weep do not wax indignant. Understand.

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

Well done is better than well said.

Be kind whenever possible. It is always possible.

Know or listen to those who know.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.
