I think life is about doing what you want, and in effect, being happy.
It also includes getting what you want, and having purpose.
Having meaning, you will be happy.
Learning, and self improvement.
For some people, they are happy, because they are trying to get into heaven. They have a purpose, and this is where I kind of stop. I have no idea, concerning, but I am happy, when I am learning about computers, and math, and geeky stuff. I guess you can never be happy.
But the Bible, the real one, not the DJ one, says that you will be happy in heaven, and not on earth.
Take that as you will, I should try to get into heaven. That's what I will try adn do, but my faith is poor.
