Roomba Philosophy, or what I learned from someone else's Roomba

This is how my friend S. described his new Roomba:

i know there is a method to the madness, but it really looks like it is thinking: ok, just, like... GO. and then, like, if you hit something, like... go in SOME OTHER DIRECTION.
and then, when you run out of battery power, go home.

It then occurred to me that this is a pretty good philosophy to live one's life by.
