I've seen this advice throughout the decades that is summed up like this: hang out with people that are more successful and smarter than you.
The reasons for this advice is that their habits of thought and action will rub off on you.
But if this advice is true, you would have difficulty following it because anyone who is more successful and/or smarter than you wouldn't want to hang out with you because well... you ain't smarter and/or more successful than they are.
And if they did hang out with you, there is a danger of your relatively bad habits dragging them down.
Thoughts that run through my head as I await the arrival of the plumber.
