Well done is better than well said.

Know or listen to those who know.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.

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

What you do today can improve all your tomorrows.

Be thine own palace, or the world's thy jail.

It's always too early to quit.
