If you're going through hell, keep going.
Quality is not an act, it is a habit.
The secret of getting ahead is getting started.
Leap, and the net will appear.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
It's always too early to quit.
If 50 percent of your career is not filled with failure, you're not really successful.
