Saint Petersburg Mathematicians and Their Discoveries

“What is the most important thing a scientist should cultivate in himself? One should get rid of excessive ambition. One should not think that only a genius can be happy. One must learn to appreciate even a small achievement, to rejoice in it, and never overestimate oneself. One has to cultivate a love for work. One has to understand and cultivate the joy of learning, which is almost the same as the joy of life. Happiness is when your life’s work is needed.”

Sobolev, Sergei Lvovich
