Wherever you are - be all there.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
I can, therefore I am.
If you think you can do it, you can.
Quality is not an act, it is a habit.
