Never complain and never explain.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
Leap, and the net will appear.
Well done is better than well said.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
I can, therefore I am.
Imagination is as vital to any advance in science as learning and precision are essential for starting points.
