Flying can be very difficult to learn for some, I myself fell into this category. When I first attempted to fly I couldn't even get off the ground, I tried and tried yet nothing happened. I eventually learned that flying, along with everything else in your dreams, needs to be mentally conquered. What I mean is, if you believe you can fly, you will fly. Believe in yourself, imagine yourself in the air, the gusts flowing through your hair. When you do make it into the air, flap your arms, put them out in front of you, do whatever it takes to reassure yourself that you are in control. When you have control of your dream you can do anything.
