It's not clear that the people doing amazing things around the world have more strengths than others who don't think of themselves as on track for amazing things.
I would suggest that it's not how many strengths we have but how we combine them in new ways. Consider the amazing wealth and variety of painting and fabric art that present new combinations and variations of just red, yellow, blue, black and white.
Each of us has literally dozens of essential strengths. All we have to do is dedicate ourselves to the art of living and working from them.
