Really, it isn't. Thank god we are not discussing a big deal here.
Everytime something irritates me, I just think to myself, "Wow, if this tiny little thing is causing me to get this annoyed, I must have a really good life."
I then take time to thank god that my family is in good health, we have a small but nice home over our heads, no one flew any planes into any buildings today.... you get the idea... These are the big deals... If any of those things happened, the little things wouldn't even register! We really wouldn't have time to indulge in the small annoyances!
This is so nothing in the scheme of things... but maybe it will help if you think to yourself the next time some small insignificant thing bothers you...
"Wow, I must have a great life!!"
Try to relax and enjoy it!!
