Interesting post.

The idea is to be happy. If you're lucky enough to find work that makes you happy--go for it! If you have a relationship that makes you happy--relate away.

As long as you're not self destructive (or destructive of someone else's self). you have the right to lead your life as you see fit. No one needs to save the world. If you live a life of positivity it's contagious and you've benefited others y example.
