it takes more than one thing to get to that level of success.
bill gates was focused.

but he had something to be focused on because
he was hooked up with a mainframe to fool around with
before most ppl knew what a computer was.

bill gates didn't earn that first mainframe computer.
he just got it and became obsessed with it.

the question suggest there is one thing that makes somebody successful.
but unless we are talking about hitting lotto,
you need at least 2 or 3 things to break in your favor
for you to make it do what it do.

i don't begrudge their answers,
but the question was phrased in a way that shows a
faulty or disingenuous assumption about how ppl become successful.
