Watch a series called American Dynasty. Many of the most successful people in history because so, in part, because a stroke of luck. They had many setbacks before they caught their break, but it was ultimately luck that allowed their venture to take flight. Had they given up sooner we likely would have never known who they were.

Yes, as they say 90% is just turning up.

Being smart and working hard might pay the bills but are not enough for 'success'. As above, it seems many if not most successful people seem to have caught a break; been in the right place at the right time, discovered some little trick or loophole, etc.
