Another secret to success: have good parenting, DNA, education, friends, and an interest in creating things of value (as opposed to the other million things you can do with your time)

Those things are harder to control, so generally less worth thinking about.

That's a pretty good point.

> creating things of value

This is extremely subjective, taking the example of dropbox, most of the comments against it at 2007 were dismissive because "it didn't had enough value".
