The secret of getting ahead is getting started.
Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Only the educated are free.
Quality is not an act, it is a habit.
If you've got a talent, protect it.
Who seeks shall find.
Either you run the day or the day runs you.
Go for it now. The future is promised to no one.
All the mathematical sciences are founded on relations between physical laws and laws of numbers, so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.
