We assume winners have the best advice, but those who win rarely examine why they won, while those who lose often regretfully dwell on their mistakes. So you’ll often obtain the best advice on winning not from winners but from losers.
Instead of trying to be the best at one thing, try to be "merely" great at two things and then learn to combine them. Not only is this easier, but it will make your skillset more unique, cutting out the competition.
