Things do not happen. Things are made to happen.

Well done is better than well said.

Do not weep do not wax indignant. Understand.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

Who seeks shall find.

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

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