Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Never complain and never explain.
What you do today can improve all your tomorrows.
The secret of getting ahead is getting started.
It's always too early to quit.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
Science is wonderfully equipped to answer the question 'How?' but it gets terribly confused when you ask the question 'Why?'
