I think I've just learned to be rather careful about who I open up to. Honestly, most of the world doesn't want to know everything going through my head, so I keep that kind of discussion limited to a few.

Call it maturity perhaps. I think it is somewhat just the result of experience and clearer perception about people now. I'm also much more personally secure and honestly don't generally want other people's opinions about my personal matters anyway. Sometimes it is perfectly okay to just handle things privately.

As far as complaining goes, I subscribe to the "not my circus; not my monkeys" philosophy most of the time. If it IS my monkey, I best have a solution if I'm going to open my mouth.
