If that’s too hard or scary to speculate: start with a chunk of lifestyle now. Not your leisure time, but your actual life. When, for example, are you happiest at work? If your answer has anything to do with others (i.e., “when I get recognition,” “when I get a raise,” “when I win a deal,” or “when I help others,” you need to look again, for answers that serve you.) Maybe you don’t even like your work. That’s for you to explore.
