One thing that I am big on is checking the motivation behind my actions (thoughts, words...) When the motivation is selfish, I try to keep the resulting reactions at bay. I'm almost anal about this. Seriously. Anal. So, when I see something like the sign above, I have to wonder who in the world would want to be happy just because it might drive someone crazy.
I'm of the opinion that selfish motivation will have Karma (the American, pop culture kind not the real one because I'm not in total understanding of the REAL karma) knocking at your door,with force. And I've got enough of that coming without adding to it.
So, I'm thinking that we should be happy because happy is fun and feels so much better than sad or angry or frustrated... But not because it might drive someone crazy. That's not nice. And it's not true happiness either.
Happiness IS an inside job. If it's not true happiness, we better check our insides.
