Today I had a breakthough. I decided it was okay to not like the things I didn't like about my job; and that I could acknowledge my feelings about them, while still refusing to dwell on them.
Interestingly, right around then I started idling browsing through LinkedIn job listings. I saw all of the awesome (part-time) jobs that required some varying years of asset management, and realized anything I don't like is far, far outweighed by the fact that I'm standing on a springboard, ready to be launched into all kinds of opportunities.
I was disappointed at first that this doesn't feel like my forever job. The hours and lack of flexbility just make it unfeasible with all the other things I want to do. But I'm finally over that, and thrilled to be in a place that allows me to go in so many directions. I changed out of my Friday casual jeans (nice, dark ones) and went merrily to work in more professional garb.
There, I stayed grateful through a few tedious tasks, a general exhaustion from cumulative lack of sleep and throughout watching the facilities manager fire two people. They needed to be fired, unfortunately, but it's always a sad thing.
So finally, my head seems to be in the right place about this opportunity. Not too attached, but able to really appreciate it for the wonderful launch platform that it is. At last; equilibrium.
