How do you control your annoyance?

I am just curious. How do you deal with things that annoy you? I am the type of person who seems to be easily annoyed; there are things that annoy me that would seem to roll off of others (like my very laid-back husband :) ) I think I've gotten better with age, but there is always room for more improvement.
I just take a deep breath, and think of other things that need to be done. I do pretty good I would say with my annoyance but sometimes when things are CONSTANTLY getting to me I am just like ugh...and I try to just think about other things.
