I'd buy land in a private, tropical place and set it all up to be completely self contained so that I'd never have to leave and could just live off of my own land. I'd have animals, but I wouldn't eat them. I'd have all sorts of amazing gardens and fruit plants and trees. A recording studio and practice space for my band, all sorts of sporting activities: tennis courts, basketball courts, etc. I'd have a nice big gym with lots of exercise equipment and wrestling mats. My land would definitely need to have forests so I could build some dirt jumping trails and hiking trails, etc.
But the best part is that I'd have places for all my closest friends (mainly the guys in my band) and their families to live as well and they'd get to enjoy the self contained lifestyle in paradise with me.
Now that I think about it, all that stuff would probably cost a lot more than 7 million dollars heh. So I guess, to answer the real question... I'd invest that 7 million dollars and wait for it to grow and THEN build my own paradise.
