It's always too early to quit.
I can, therefore I am.
Begin to be now what you will be hereafter.
You never know what motivates you.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Only the educated are free.
Either you run the day or the day runs you.
Leap, and the net will appear.
In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.
