"Don't sweat the small stuff. It's all small stuff".

It's about adjusting your perspective. Some things can be looked at as new challenges and opportunities for creativity. Some things can feel very important and weigh on you but given a day or two can be irrelevant. Other things like death, finances, or relationships are difficult to get past, but you will eventually. Taking a breath to step outside the situation or looking at it from someone else's perspective can really help.

I absolutely have these little moments every day. I get mad, say some 'what the fucks' out loud, call myself an asshole, etc, then move on seconds later. Giving your emotions a reasonable amount of time to smack you up is a good thing. Allowing them to take over isn't helping anyone.

Edit: Come to think of it, I was just around my mother for the holidays. She is agent of chaos. She has a short temper, she yells, she's erratic, she very much exerts her irrational stress upon others. Without getting into my entire childhood, I'll share that it took me many years to figure out why I was so short tempered and angry at everything. The quote I started this post with was what sparked the change for me.
