Newton, by the age of 25, has had invented the laws of motion and calculus was incubated in his head. Fourier, by the age of 30, has had written monumental works on thermodynamics and mathematical physics. Einstein, at the age of 26, published his special theory of relativity. Looking at these great giants, it seems like the period between age 20 and 30 is the most creative and productive period of one’s life. Now I am complaining about the workload, about the amount of knowledge I need to assimilate. When I think of these figures, what rights do I have to complain? I should really seriously treasure the time right now, and learn as much as I can, try to find as many interesting problems to solve as I can, and try to get exposed to as many facades of life as I can. I am in the prime time of my life, and I should feel guilty by wasting any second of it.
