SWIM suggests pretending to take fake donations toward a cause (door to door or a public posted box) and then keeping the money, stealing things like phones and then selling them, selling drugs, carding, stealing from stores (really easy if you select your store right and are going for the right product) then selling on ebay or some stuff, printing off coups and then reselling couponed items, phishing sites, pick pocketing, mmo account hacking and then selling, and much much more. Of course, if you want to do it legal... get a job you lazy forget
