I get very frustrated when I find people don't meet my expectations of them.
This is and has been an ongoing problem for me, one that I've only since begun to realise. It's also the source of a lot of my frustration and stress in the past, particularly when leading.
I think I have a great idea of how the outcome should be, and once that doesn't materialize, I revert to a self-pity mode, where everyone else is the bad guy and I'm all-there-where's-everyone-else-why-arent-people-seeing-things-similarly.
I find its ultimately to the detriment of the ongoing process, and its discouraging to others as well as myself.
