Hence the "stick with it and don't screw up" caveat.
But seriously... Look at pro teams that exist now:
VICIOUS, Heat, X-Factor, Impact, 187 cRew, CEP (and probably some random teams from NPPL, but I don't care abou that league)... They all exist because of a dad who has the money to make it happen. All the other teams have an angel behind the scenes who's funding them also.
So, I'll alter that tip: Either find a kid with a rich dad, or make friends with a rich person who already has enough boats and cars.
If you can't do that, then just play with your friends and have fun doing it!
