I was frustrated by certain aspects of how my team was run, so when that position became available, I applied for and moved into it, thinking I could make some changes that would make the team function better.
I did make some of those changes and they have helped, but I've also found it really challenging to carry responsibility for delivering things that I can't work on directly. I used to solve problems by writing code; it's much different to solve problems by coaching people.
I do have stronger relationships with my colleagues now, since I spend more time communicating with them vs. being head-down in code all the time, and that's kind of nice, but I'm definitely missing the hands-on work
