If you've got a talent, protect it.
If you're going through hell, keep going.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
You never know what motivates you.
Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
In science there is only physics all the rest is stamp collecting.
