The Serendipity Equation

success of a project = project potential  x  serendipitous factors

Summary: You cannot count on luck or skill to generate remarkable outcomes in isolation. The most consistent path to meaningful accomplishment seems to be a combination of the two. Pick a small number of things and become so good they can’t ignore you. Along the way, however, keep taking your growing skill out for a spin, launching related projects, one after another, carefully studying the outcomes to see if you stumbled into something big.
