A friend of mine put it in fantasticly straightforward words:
“Do what the most successful person in your business does.
Then you become successful.
And have a Porsche.
And you do models.”
Nothing to add here.
But this is not enough to endure at the top, because it’s not enough to just remain as good as you are. The next in line is already about to do the same (more success–bigger Porsche–hotter models), and most likely more motivated to accomplish it.
