Next time something like that happens, start with more traditional ways of eradicating what you don't want. Grab a gun and shoot the bear, or if you can't find a gun, go over and confidently kill it with your *bear* hands. Anyway once you get comfortable that you are in control you can do harder things more easily. If you want to fly, don't think about not being able to fly. Assume you can fly. Even imagine that the gravity is reversing and there's nothing you can do about it, you will have to fly now!
