Know or listen to those who know.

Either you run the day or the day runs you.

It's always too early to quit.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

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

The most effective way to do it, is to do it.

If you think you can do it, you can.

Do not weep do not wax indignant. Understand.
