I can, therefore I am.

Things do not happen. Things are made to happen.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

You never know what motivates you.

Quality is not an act, it is a habit.

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

Be kind whenever possible. It is always possible.

What you do today can improve all your tomorrows.
