If you're going through hell, keep going.
You never know what motivates you.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Never complain and never explain.
It's always too early to quit.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
With improvisation, I just do it. It might be a total failure but then you just throw the dice again.
