By failing to prepare, you are preparing to fail.
Go for it now. The future is promised to no one.
What you do today can improve all your tomorrows.
After a storm comes a calm.
Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
Begin to be now what you will be hereafter.
Well done is better than well said.
Problems are not stop signs, they are guidelines.
Leap, and the net will appear.
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.
