Begin to be now what you will be hereafter.
After a storm comes a calm.
Well done is better than well said.
Only the educated are free.

Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Be gentle to all and stern with yourself.
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.
