If you're going through hell, keep going.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
Quality is not an act, it is a habit.
Leap, and the net will appear.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
