Happiness comes from within

Am I happy?

I enjoy what I'm doing, but does that mean I'm happy? To do a whole day of stuff, running to and fro, doing this and that; but now sitting down and thinking about it, was it all mindless stuff that I was doing. Was it all done so often, so often to the extent that it has become routine-like and doesn't require much brainpower to do anymore? Does is mean that I'm happy doing it? Or just contented? Or just, without thought?

Idk.
