By failing to prepare, you are preparing to fail.

It's always too early to quit.

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

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

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

If you're going through hell, keep going.

Know or listen to those who know.

Things do not happen. Things are made to happen.
