Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
Always desire to learn something useful.
It's always too early to quit.
Wherever you are - be all there.
Never complain and never explain.
I acted in theater and I took film classes when I was 12 and just obsessed over it. I loved it and spent hours and hours in the film studio learning and watching.
