"Flying is the art of learning to throw yourself at the ground and miss. All you have to do throw yourself forward with all your weight and the willingness not to mind that it's going to hurt, that is, it's going to hurt if you fail to miss the ground. Most people fail to miss the ground and if they are really trying properly they fail to miss it fairly hard.
You have to miss the ground accidentally, it's no good deliberately intending to miss the ground because you won't. You have to have your attention suddenly distracted by something else when you're halfway there so that you are no longer thinking about falling, or about the ground, or about how much it's going to hurt if you fail to miss it.
If you can accomplish this you will find yourself floating a few inches above the ground in a slightly foolish manner. Bob and float, float and bob. Ignore all considerations of your own weight and simply let yourself waft higher. Do not listen to what anybody says to you at this point because they are unlikely to say anything helpful. They are most likely to say something along the lines of, 'Good God, you can't possibly be flying!' It is vitally important not to believe them or they will suddenly be right. Try a few swoops, gentle ones at first, then drift above the treetops breathing regularly. DO NOT WAVE AT ANYBODY.
When you have done this a few times you will find the moment of distraction rapidly becomes easier and easier to achieve. You will then learn all sorts of things about how to control your flight, your speed, your maneuverability, and the trick usually lies in not thinking too hard about whatever you want to do, but just allowing it to happen as if it was going to anyway.
You will also learn about how to land properly, which is something you will almost certainly cock up, and cock up badly, on your first attempt." -The Hitchhikers Guide to the Galaxy by: Douglas Adams
