Little annoying things can pop up anywhere, any time. Delays, distractions, electronics and computers not working how they're supposed to...it can get very frustrating!
Don't let it get the best of your mood. If need be, put yourself in a little time out to get recentered.
Controlled breathing is a quick and easy way to bring back the calm. Inhale for a count of 5, hold just for a second, exhale for a count of 5. Repeat three times.
This signals your brain to cease the release of all the overproduction of stress hormones and tells it that everything will be fine. Still delayed, distracted, or annoying, but fine.
If you allow those things to get to you, you'll be closer than need be to snapping at someone who doesn't deserve it and you'll be polluting your body with stress hormones that will make you feel drained and tired later on. Taking a few moments to recenter will reframe your mood and your mind and put you back in full control.
