motto

Do you have a motto or a one-line life philosophy? I don't, but I'd be interested to hear what you guys have to say. If you can, please elaborate on why you relate to it/how it has affected you/where, when, and how you adopted it.

As the title indicates - Which mantra(s)/ motto(s) do you live by, which you feel are pertinent to an INTP type? Just to help get things started: "I don't go along to get along." {P.S. That doesn't mean i'm not open to ideas, just that they have to make logical sense and/ or be rational}
