Man is driven to create; I know I really love to create things. And while I'm not good at painting, drawing, or music, I can write software.

I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language.

I didn't work hard to make Ruby perfect for everyone, because you feel differently from me. No language can be perfect for everyone. I tried to make Ruby perfect for me, but maybe it's not perfect for you. The perfect language for Guido van Rossum is probably Python.

It is not the responsibility of the language to force good looking code, but the language should make good looking code possible.

The orthogonal features, when combined, can explode into complexity.

Plant a memory, plant a tree, do it today for tomorrow.

Often people, especially computer engineers, focus on the machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines.
