" I wonder if people have an innate preference for one strategy or the other based on their personality type" Probably. But what I have learned is that you cannot optimize only for the one side except you are extremely good at that side and extremely hopeless on the other side. There was a time when I thought I am 'smart and shy', so I should clearly optimize on being a 'quiet professional'. But later I've met really-really smart and hardworking people, without a doubt smarter and more knowledgeable than me. Kind of best in 100000s. They became mostly researchers, and they are not 'recognized' enough (with money at least) compared to how smart and professional they are. I think 'be a quiet professional' is a good advice for being a researcher for example at Microsoft Research, but if you want to make a lot of money it is not the best advice.
