You're also not seeing the financial, familial, or other lucky breaks that may have aided their success.
Sivers's video also hints at the futility of striving for “originality” or wishing you had “talent.” Perfectionists often perceive themselves as lacking these qualities, but they're really beside the point. What counts is doing the work and letting it take you where it wants to go. In other words, talent and originality aren't the foundation of good work so much as the yield of it.
Does this mean that every piece has the potential to be a winner? Of course not! But you can't force it. Forcing is inimical to the creative process. Or, as Flaubert put it, in the quotation I probably cite more often than any other, “Success must be a consequence, never a goal.”
Many thanks to Ben Seeley for bringing the Sivers video to my attention!
