Hmm.. I think the point is that people can accomplish a lot more when they are playing instead of working. I think the strategy works as long as you produce results that are better than your peers. Sure mgmt/profs will complain how your estimates/proposals are always inaccurate, but ultimately delivering results is what matters. It's a risk of course; certainly the less travelled road, but I don't think you have to be feynman for the strategy to work. You do, however, need the abililty to "not care what other people think," which is part of the title of another one of feynman's books.
