Successful != typical, or even average in this context when referring to folks that start.

If you’re looking at starting, it’s helpful, but it’s important to not delude ourselves either.

Having more life experience helps, but when the funnel has a > 90% overall attrition rate, it’s still far from a sure bet.

Part of the reason why the older folks tend to do better IMO, is it’s more likely at that age that they know their own capabilities better and are less likely to launch down a path they’ll definitely not succeed on, and the numbers reflect that more.

It doesn’t mean automatically everyone once they hit that age will have those odds.

There is a lot of self-selection bias going on.

Possibly some but not that much. The linked research states that the age is still up at 42 when you remove "successful", and still 40 if you then add "software".

Interesting, thanks for the correction. Apologies for not RTFM’ng first.
