If you are disillusioned with your life/ work, dont aim to be a manager. After each day (or worse, week) looking back on what you *did*, managers tend to draw a blank. Meeting a deadline is a task. It will come and go, to come back again. Another regular task is to resolve issues (read fights). Someone or the other has a problem with another. Or someone had a bad day. Manager’s job: Listen; Resolve; Repeat. Much like a detergent. And tumble around.
