I d study economics and maybe psychology, as to deal with money better and dealing with clients. It would probably take a long time to become as successful as Ari. Word travels fast though, so one big client might lead to another, and another, by word of mouth and so forth. With perseverance and not afraid to lose a bit of money at first, you may eventually become as big as Ari. It would be tough though.
You would need 10 to 20 times that initial investment to compete with the bigger ones. 5 mil? Forget it.
