What is your greatest Fear?

I have so many fears in myself I have fear of public speaking but eventually after trying hard to face this fear it's now lessened in degree. And now my greatest fear is fear of encountering new experiences, this fear isn't easy for me to cope because every time I have to face new experience I just escape from it because I always felt I wasn't yet prepared for it, until I would regret again for not giving myself a chance to face this risk and and realized my potential.

The greatest fear I experience is when I start loosing confidence in myself. Self confidence is my greatest virtue with which I lived for 40 years (forget the first 10 years) and it delivered the goods.
