Wherever you are - be all there.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
If you're going through hell, keep going.
Well done is better than well said.
Begin to be now what you will be hereafter.
Be kind whenever possible. It is always possible.
Go for it now. The future is promised to no one.
Never complain and never explain.
If you think you can do it, you can.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
