The most famous one is the computer player. Are you kiding me? Some people manage to live only by playing computer games! In North Korea there are even national champioships of computer games that pass on TV all day and night long. Most of these players have no life except the computer life. They live to play. Sure they make a lot of money but NOTHING pays enough that you waste your life in the computer all day and night.
You know that in China some people are paid to Play World of War Craft and then they sell their accounts on eBay and other online businesses. The truth is that if you have money you have pretty much everything. Probable the most important thing in computer games is the reaction time. If you can react faster you can win any game. Most skill games are just time reactions games. You need to be the first to drive, or the first to shift or the fastest doing something. The only exception for this is probably the turn based games but even so many have time limits and you do need to think fast,… very fast!
Speaking of turned based games. Have you ever tried Civilization from the one to the two and three? The game is awesome. The second version even has an integrated cheating option so you can use the cheats to have even more fun. The cheats are great for you to see how the game is exactly build and how stupid people are when they seriously consider the computer games.
Another good career in computers is the programming one. A good programmer can make a lot of money not only working for someone else but also on is own with a website or something that where he can sell his games. A good website with lots of programs to sell can make a lot of money and even if you offer your program free you can still make money with Adsense and other advertising programs. The price is not cheap: Long hours of work and more. The more you work the more you can do. Everyone can teach you that.
Finally you can make money and a career by selling things online. You are required to have an email plus some other account and then you are done. Most people know nothing about making money online so you have a great advantage over them. You already know someting they don’t so use it at your best advantage. If you can write goos content you make make a lot of money with jsut Adsense and other advertising programs. The best business model is the one that gives you the most money per month folowed by the most per thousand visitors.
