Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Wherever you are - be all there.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
If you can dream it, you can do it.
Well done is better than well said.
Be kind whenever possible. It is always possible.
I broke down while at Oxford, was rejected by a record number of medical tribunals during the War, and finally got permission to leave Oxford and do civilian work till the War ended.
