I've always had a hard time with air. Before I even get near a jump, I get nervous, I can imagine going off and messing up,landing on my neck with my bike on top of me,all the blood,splintered bones, I can imagine all of these. Needless to say I have a hard time with jumps. But on the other side of the hand, I always enjoy jumping when I get up the nerve to go over. Like back when I would skateboard off the roof, took me a little while, but once I did it I loved it. What's a good way to start with jumping? Are my imaginations normal? Do I just need to practice some mind over matter?
