Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
数学不仅仅是关于数字、方程、计算或算法,而是关于理解。
If you are ready to give up everything else and study the whole history and background of the market and all the principal companies whose stocks are on the board as carefully as a medical student studies anatomy—if you can do all that and in addition you have the cool nerves of a gambler, the sixth sense of a clairvoyant and the courage of a lion, you have a ghost of a chance.
History does not repeat itself, but it recurs in different forms.
Life is an adventure, it’s not a package tour.
The only thing that can make you happy is doing what you love.
