Wherever you are - be all there.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
Be gentle to all and stern with yourself.
Do not weep do not wax indignant. Understand.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
If you're going through hell, keep going.
Never complain and never explain.
