>both Bill Gates and Warren Buffett, two of the most successful men in history, are both seemingly dedicated to their families.

So the richest (for most part of time) and second richest man have privilege to spend time with family? What a surprise

>Success is also a subjective term

Let's not play the word game, if you made a billion dollar last year. You are successful, this is pretty much the normal definition of it. Don't change it to fit something like family matters, community matters or noble purposes imho
