Life is meant to be enjoyed. Sure, I agree with this statement (as many of us would) but the problem is this is used to justify all kinds of crappy behavior.
Do not excuse the crappy you keep in the name of 'joy', they are still crappy. You can give up pretty much anything and still enjoy life, cause joy is inside you, can not see it in your pictures or you can not post it on your Facebook page. Do not be jealous, most of people keep posting ain't to be happy....
