First of all, you shouldn't start with anything with the expection to be extremly successful.
For starting, I think you should might think about which thing you can do good and like to do (like for example hacking, drug production, burglary, scam, weapons, carding whatever).
Then inform yourself about the thing, try to get every information possible, really invest much time doing so.
Then start in a small scale, for example when you want to make business with hacking, first try to do a simple hack like Wifi password or account password.
Try to scale up with time and also really important, look for cooperations and partners, otherwise you won't ever be successful in long-term.
