Most editors treat everyone the same. Emacs, on the other hand, becomes
uniquely yours – tamed, like the fox in The Little Prince. Let me paraphrase:

“No,” said the little prince. “I am looking for friends. What does
that mean—'customize'?”

“It is an act too often neglected,” said Emacs. “It means to
establish ties.”

“‘To establish ties'?”

“Just that,” said Emacs. “To me, you are still nothing more than a
user who is just like a hundred thousand other users. And I have no
need of you. And you, on your part, have no need of me. To you, I am
nothing more than a editor like a hundred thousand other editors. But
if you customize me, then we shall need each other. To me, you will be
unique in all the world. To you, I shall be unique in all the
world…”

And that is why I like Emacs. It may not be the perfect editor, but
it's _mine._ =)
