The backflip analogy works very well. Learning a backflip on the ground, you really have to overcome two obstacles. One of them is the technical side - jumping straight up, tucking quickly, and landing. Not extremely difficult to master.
The most difficult part of doing a back flip is getting over the fear. The thought of going backwards, jumping and leaning back into the unknown, committing one hundred percent, and the constant stinging thought of something going wrong.
This is exactly like an approach. The truth is, once you commit, spend some time learning and forcing yourself to devote some time, you do land it, and you realize that it is possible for you to do.
Here is my similar 'Backflips and Game' post I put up a few months ago.
