The market seems to reflect that age is a valuable attribute for entrepreneurs[1], and I'd be curious to know the average age of published authors, composers, mathematicians, and so on; particularity when it comes to works that society deems important long term. But anecdotally I'd say that an individual's future potential is more interesting to society at large, based on prevalence in the media and the social cachet of hanging around with people in the 30 under 30 crowd.
I also think that success is too broad a term to characterize generally, but if you think about different opportunities and pressures in each logical window of time in an average person's life then it should be apparent that different varieties of success are more probable for each timeframe, even if chance contributes on an equal basis with any other personal attribute.
In any case, being comfortable with wingin' it is probably itself a favored characteristic.
