I feel that the title is somewhat deceiving, because this is not about happiness being boring but about the fact that one must bring some effort in order to be genuinely happy.
With regards to the words about Facebook, I largely agree. However, I also think that this social network is misused by the most, and that if it were used wisely, it could help build out happiness. Here I mean that staying in touch with others (and actually messaging each other), staying informed via your newsfeed, joining groups of mutual interest or popularising a product, company or even your writings, are better ways of using Facebook. The problem is, most people use it not to stay informed about their society but to peek into their neighbour’s life.
So, now that I think it through, Facebook only reveals our bad sides, rather than creating them. Don’t you think?
