Things do not happen. Things are made to happen.
Never complain and never explain.
Begin to be now what you will be hereafter.
I can, therefore I am.
You never know what motivates you.
Who seeks shall find.
The wise does at once what the fool does at last.
Always desire to learn something useful.
The dog that trots about finds a bone.
Well done is better than well said.
In 1948 I entered the Massachusetts Institute of Technology, undecided between studies of chemistry and physics, but my first year convinced me that physics was more interesting to me.
