If you think you can do it, you can.

It's always too early to quit.

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

Do not weep do not wax indignant. Understand.

If you can dream it, you can do it.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

Well done is better than well said.
