Cameron Herold argues against overplanning your career. Instead, stay opportunistic, build your network, and seek learning wherever you find it. The right path reveals itself through experience, not spreadsheets.
Don't overthink it. You don't know where you're going to end up 10 years from now. Don't try to plan too hard, because otherwise you may totally miss the best thing that ever could have happened to you. Be opportunistic. Build your network. Keep looking for new opportunities to learn. Surround yourself with people that can teach you things. Those opportunities will present themselves and they will teach you what you love to do and therefore what you're best at. And then you can start to focus in on those things. I feel very fortunate I end up where I did, but I wish I'd known that early on.
