If you're coming from a technical role, understand that your new job is not to be an engineer. If you're lucky and are good enough at your new job that you have some spare cycles, you might get to guide some architectural discussions
It can be rewarding to help guide a team towards something you could never accomplish alone, but you must resist the temptation to step and do "do things".
Disclaimer -- I moved up to a director-level position and realized within a year that to be good at it I would probably not be able to continue expanding my technical skills, at least not on company time. I moved on to an "individual contributor" role with a company that provides higher level career opportunities that don't involve having direct reports. The minutia of actual line management wasn't bad as long as there was a good team, but I definitely underestimated the people skills, budgeting, planning, and politics that goes along with being a good manager.
