Devote time to study Power Prospecting - be and act like a pro- for now forget mailings, silly yellow letters and hand written notes mailed to owners - be pro active - go to auctions, call or knock on doors of expired listings and FSBOs, get a tax sales list for your county - walk and talk and drive for deals.
