My knee-jerk reaction would be “if you’re happy”, but I had an epiphany a while back:
I was chitchatting with a coworker over way too many beers and he asked me something along the lines of “were you happy growing up (insert background here)”, and after weighing my words I responded that “I would’ve been, except I’m generally not a very happy person”.

So am I satisfied with my life? Yes.
Do I have worries? Yes, like anyone else on this planet. Mine are pretty minor and not debilitating.
Do I consider myself happy now? See above.

But yet, I’d conclude that I’m living a good life, even if I’m generally a grumpy guy.
