Keeping it shut

I'm reminded of a Malcolm in the middle episode (now contemplating life as it relates to television, not a high point)in which he decides to not say the first thing that comes to mind for a while, in order to be ..nicer?... to the people around him. I'm trying to adopt a practice of not complaining when something hurts me or makes me unhappy. This may not be the best approach, but I'm tired of feeling like I can never be made happy by the things around me, and tired of feeling as though I make other people feel as if nothing they do is right or good enough. I'm not very good at not wearing my heart on my sleeve, though. I don't want to feel as though I'm being dishonest, but I don't want to make other people deal with what are, essentially, my problems. I don't really feel I can share the stuff either, since the ones I would be inclined to talk to about it are the ones who would be affected by them. On the other hand, at least no one I know has been swept away by a tsunami, so life can't be too bad.
