The pursuit of knowledge is a never-ending journey.
The only thing that can make you strong is your own will.
Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.
I will tell you what I will do and what I will not do. I will not serve that in which I no longer believe, whether it call itself my home, my fatherland, or my church: and I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defence the only arms I allow myself to use—silence, exile, and cunning.
