Whenever you experience fear observe your thoughts, how your body is responding, how your breath is changing and the kind of emotions (of course negative emotions) rolling. Get deep into each of these areas and observe them deeply. Once you observe deeply you would realize that your mind and body are acting certain way based on the intensity of the fear. You would understand that you are getting stuck with this very uncomfortable experience and not able to move forward to take decision, action and think clearly. Practice this experiencing fear in detail for your fears and you will get comfortable with the uncomfortable experience. Soon you will be able to conquer your fears one by one. It becomes kind of norm to feel uncomfortable but the biggest difference is you move forward unlike earlier.
I have experimented this . I went for paragliding near Himalayan mountains (near Dharmasala). I have never done much of adventurous sports earlier. I felt nervous initially. I tried to implement the theory a bit into practice. I have noticed how my body reacted initially in detail and after some time I got some comfort and jumped ahead finally. It was very scary when the pilot tried to do some sudden jerks in the middle to create “excitement”. But at the end it was very much fun and got some comfort.
