I think now that I'm older, I for sure take more ownership of it than I perhaps should. I find myself constantly brooding and figuring out why I messed up this or that, how to fix it. I'm not perfect, but I think as I've gotten older I for sure see my shortcomings in a lot of things. It would be good to be able to improve them, and some do, but others end up taking more time. In my younger years I didn't think of many of them as learning opportunities but these days I for sure do!
It's unfortunate when you see those things happen. I've seen people at the workplace blow up and it sucks. It isn't conducive to interpersonal relationships. Not that it isn't always unnecessary, but getting to the point of blow up isn't a good thing. Gradual release valves are what people need, myself included!
