To know oneself, one should assert oneself.
Wherever you are - be all there.
Leap, and the net will appear.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
The most effective way to do it, is to do it.
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.
