Turn that fear that you have of the future into excitement for the future.
They are both identical reactions/emotions only utilized by our bodies and minds in different ways and for different reasons. If you take control of your fear and make it work for you, instead of against you, in a short period it will turn in to excitement and you will be able to do anything.
Think of it this way... many people fear jumping out of the plane the first time they go skydiving. Heck many people won't go skydiving at all because of fear. However, once that first jump is made, they always want to do it again. They love it. They almost crave it. They get excited when they plan another jump. That is the effect of turning your fear into excitement. Once you do, the world looks like a totally different place!
