What are You Afraid the Most

I am pratically fearless at work. I think little of my colleague's fear of pissing of client/coworkers. I am not afraid of snakes, spiders, or cockroaches. Death, oh, maybe, if it is not a prolong, painful one, I think I am OK with it. I think I am afraid of not being able to live up to my potential. I guess it is time for me to write my Japanese lesson home work.
