You have to identify something specific and then look at that specific factor across the entire population of companies.
If you survey all CEO's of the Fortune 500 you might find that they are all workaholics. Do you conclude that being a workaholic will make you a CEO? Of course not. Did you look at how many workaholics there are that don't become CEO? That is survivorship bias.
You also need to look at cause and effect. Is it that you must be a workaholic to become CEO? Or is it that as you climb the ladder you end up working hard and harder because that is a requirement of each position. Maybe being a workaholic is an effect of climbing high.
