Or trying to open the front door to my apartment with the mail key or better yet, the bulky key to my car on a day where I'm tired, quite stressed or just distracted.
My face or scalp starting to itch just as soon as I get a fresh coat of paint applied to my fingernails.
Or as I'm not so patiently sitting in the floor or on the couch, forgetting my nails are still not completely dry and grabbing my phone when a notification goes off. This will undoubtedly smudge my polish leaving me to decide whether to leave it or start over on that nail and fix it. (Unless it's really noticeable to the point that it will bother me, I leave it, because I don't care that much.)
Putting away groceries and then BOOM, I remember that other thing I definitely needed to forget but forgot.
Sometimes, I forget to put the juice back in the refrigerator and don't realize it until I'm back home from work much later that day.
I've put my keys somewhere other than where they usually go when I've got a lot of things in my hands when I come in and now I just don't know if I'll EVER SEE THEM AGAIN.
Forgetting to stop by the store for some item I want or need on the way home from work.
I set my alarm for 5 PM instead of 5 AM and wake up after 6 AM in a panic with very little time to get ready. (On these days, I'm especially thankful I live 5 miles from my job.)
These are just a few examples of little mistakes and small annoyances that occur in life. These things can be quite inconvenient and downright annoying. I could get angry or let myself become filled with annoyance and become grouchy for a short amount of time. (Or a long one if a lot of them happen in a short span of time.) However, I don't focus on things like that and let them have that kind of power over me. I don't see a reason why a little annoyance should ruin my mood or wreck my day. This is definitely easier said than done, at first. It's like anything else though; once you make it a habit, it's no problem at all.
"Shit happens" is something I've heard adults say since I was a little kid. I didn't understand it then but I get it now. Sometimes, shit happens.
I think a lot of people get too caught up in the little things when it comes to what they let get under their skin. Sometimes, if you've had a bad day and a lot of things have gone wrong, it's hard not to let the little things just get to you. They're the annoying little ants trying to take away the little crumbs of happiness and peace you have left after a trying day and it's hard not to blow up and want to smash them with a hammer as if they're these large, terrible things coming at you. For me, I've learned to just breathe and try to keep things in perspective. I've made a habit of stopping, taking some deep breaths, really thinking about what the annoying this is and then deciding how I'm going to react and handle it. Usually, it's just something to laugh off and let go of. These things are like papers being stuffed into a binder. If you hold on to them, seething and remembering them and holding on letting them continue to be a part of you, you're going to get to full and then everything is going to come spilling out in a big mess or in short spurts of little explosions.
So, as trite as it sounds, I don't sweat the small annoying stuff or minor errors I make because they don't really matter in the long run. You can't control everything that happens to you and you can't even always stop yourself from doing something stupid or doing something annoying. You can control how you react and how you let it bother you, though. Letting something so trivial steal any bit of happiness isn't worth it. So when I do something that doesn't really hurt anything or cause any real issues, I just laugh it off because I'm not going to remember tomorrow anyway so I'm not going to let it bother me now.
