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

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

Most programs are not write-once. They are reworked and rewritten again and again in their lived. Bugs must be debugged. Changing requirements and the need for increased functionality mean the program itself may be modified on an ongoing basis. During this process, human beings must be able to read and understand the original code. It is therefore more important by far for humans to be able to understand the program than it is for the computer.

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.

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.

Smart people underestimate the ordinarity of ordinary people.

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