I’m building a new department to scale out services that I solely did under another department. Coming from a small company in a specialized field this means that my attention is split between managing the few under me, still actually doing the work and other admin BS. As a former doer and control freak the hardest thing has been getting out of my peoples’ ways and untangling myself from the work.
A close second is, as previously pointed out, eliminating as much additional business BS as possible. Our current director likes to really have communal discussions on business direction and development, which I’m not opposed to, but the number of meetings is too much. I’ve been clawing back my time ever since the transition.
