Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
The dog that trots about finds a bone.
Begin to be now what you will be hereafter.
Never complain and never explain.
I can, therefore I am.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
Know or listen to those who know.
I don't want to be a 'teen star' because so many people don't ever grow out of that.
