I really enjoyed this video (about 30mins) about how SpongeBob lives a simple life that he is happy with. He cooks burgers for a living, and is excited to do that in the best way he can. He thoroughly enjoys simple activities with friends. And, while he is imperfect, he has high optimism.
With social pressures and forces these days, I do believe these kinds of simple ways and values may lead to one of the healthiest kinds of lives.
