Be kind whenever possible. It is always possible.
Know or listen to those who know.
You never know what motivates you.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Wherever you are - be all there.
Go for it now. The future is promised to no one.
Never complain and never explain.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
