Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
Be kind whenever possible. It is always possible.
The wise does at once what the fool does at last.
It's always too early to quit.
Leap, and the net will appear.
Well done is better than well said.
I can, therefore I am.
If you've got a talent, protect it.
I've learned to think in terms of having a long career. Actors can have very long careers that last until the day we die, but there will be moments when you'll feel like you're a failure or when you're disappointed in yourself.
