Never complain and never explain.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
Well done is better than well said.
You never know what motivates you.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
There are no dreams too large, no innovation unimaginable and no frontiers beyond our reach.
