What you do today can improve all your tomorrows.
If you can dream it, you can do it.
Go for it now. The future is promised to no one.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
You never know what motivates you.
Only the educated are free.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Crabbed and obscure definitions are of no use beyond a narrow circle of students, of whom probably every one has a pet one of his own.
