Things do not happen. Things are made to happen.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

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

By failing to prepare, you are preparing to fail.

Leap, and the net will appear.

Always desire to learn something useful.

You never know what motivates you.

What you do today can improve all your tomorrows.
