9th- getting together with other great people

Getting together with great people is very important, their greatness will rub off on you, making you greater. It doesn't matter what they are great in, as long as they are great. They can be great chess players if you are a nerd, or if they are great in any other sport.

Not only is it important for the rubbing off, but when you become a famous tennis star having great followers will be very important. Great followers have great followers, so they will follow you too.

And of course having followers mean money. So good luck with that.

Oh and yeah, it must be at least six great people. Au revoir.
