There's more to life than having fun?

I would venture to guess that about 65% of the worlds population, when asked, would say that the point of life is to have 'fun'. If you ask them questions like, "Why do you have a job? That's not fun." They will answer with something like, "I have a job so I can make money so I can have fun."
Well. I'm sorry to ruin the ride but life is certainly not about fun. In fact the idea of it doesn't even make logical sense.
For example. People 'love'* toilet papering trees around Halloween. They think it's fun and they get a kick out of it. The thing is, you may be having fun but you are hurting someone else when you do something like that. My point is, people say that life is about having fun when they really mean, "Life is about me having fun." There's a big difference.
I, as a Christian, believe that ones goal in life should be to glorify God in everything you do. This certainly doesn't mean that you can't have fun. Fun just isn't the purpose. If in bringing glory to God, you have fun, you can be sure that you are not hurting** anyone.
Please don't read into this that I'm saying you can never plan to do something that's fun without studying the bible for a third of the time and praying for another third. I'm just saying that when having fun, you should have a purpose, and you shouldn't be hurting anyone.



*I will talk more about love in the future. All I'll say for now is that that word doesn't fit in that sentence.
**By "hurting", I mean, "does them harm". I don't just mean it offends them.

Sin!

Most people would say that sin is when you do something that your not supposed to or don't do something that you are supposed to do. The big question is, "Who decides what's right and what's wrong?" Any Christian will tell you that God does and this would be correct.

My big issue is not with who decides what's right and wrong (that's obvious), but I would venture to say that the above defenition of sin is incomplete. Let me just use an example situation.

Billy wants to go hang out with his friends. As far as he knows, he isn't allowed to but he goes anyway.
Now. If he was mistaken and he is actually allowed to go hang out, has he sinned? I mean, he was allowed to go right?

These verses would seem to shed some light on the matter.
Rom.14:22-23
" 22So whatever you believe about these things keep between yourself and God. Blessed is the man who does not condemn himself by what he approves. 23But the man who has doubts is condemned if he eats, because his eating is not from faith; and everything that does not come from faith is sin."
James 4:17
"17Anyone, then, who knows the good he ought to do and doesn't do it, sins."

It would seem clear then that sin can be as much an attitude as it is an action.
