I can, therefore I am.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Never complain and never explain.

Always desire to learn something useful.
If you can dream it, you can do it.
If you think you can do it, you can.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
