Well done is better than well said.
Be gentle to all and stern with yourself.
After a storm comes a calm.
I can, therefore I am.
If you think you can do it, you can.
Quality is not an act, it is a habit.
It's always too early to quit.
The most effective way to do it, is to do it.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
With improvisation, I just do it. It might be a total failure but then you just throw the dice again.
