I like your definition of happiness as it is a difficult thing to define.

Perhaps in your post I should have noticed that you mentioned Flash Mobbing as a break from stress to find your motivation again--to recharge your batteries. Instead, I thought you were saying we should take time out for ourselves sometimes.

Personally, I think the greatest service we can provide to the world is finding ourselves; we can most help the world by spending our time making ourselves happy, even if we accomplish fewer things in this manner.

I think the people who need flash mobs, or other random distractions, the most are the people unsatisfied with their lives. I think these same people may need new careers or new passions to pursue. However this is an idealization of the world. We cannot have everything we want and we cannot always change our careers or lives.

It is as unfortunate as it is true that people need money and cannot paint or flash-mob all day. Sometimes happiness has to be set aside in order to fit in with society.

How would you feel about a person who not only was willing to spend 5 minutes a day doing something random and fun, but also willing to spend 8 hours a day doing nothing productive and instead merely chasing silly pursuits?

Flash mobs, and other unconventional events, add happiness to society and to peoples' lives but do these people have any obligation to society to stop flash-mobbing at some point? Would it be okay if a person only chased happiness and sat in a room painting or watching movies for his whole life? I don't see any reason to go back to work if flash-mobbing makes people happy
