It's always too early to quit.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

Quality is not an act, it is a habit.

Begin to be now what you will be hereafter.

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

If you've got a talent, protect it.
