With drop shipping it is often difficult to make a good margin because those markets are generally over saturated, however, there is always room at the top ;). I would recommend finding something that you enjoy doing as a hobby and turn it into a business. Generally, the more you know about a given industry or topic, the better you will do starting a business in that industry. If you are good a video games, do something related to video games. If you are good at problem solving, then try focusing on solving a customer or business' pain in an industry of your interest.
