I feel I live free of the possibility of genuine fear, mostly. I don't fear rejection, failure, loss, or death, because of reasons.
I make it a point to think about decisions before I make them so I can't regret it whatever happens, however insignificant any decision is to me at the time I make it. I may not always take decision-making seriously, but I'm not going to curse myself over something I did in the past--whatever the impact may be, and however idiotic and asinine I may have been (or be). I accept or move forward. I can reflect and laugh at myself.
Naturally, that means if something happens that I didn't--not merely couldn't or had no other way to--stop, I won't despair because of it (though of course this doesn't mean I won't try to help the situation). This relates to my thoughts on death.
And just as everyone else, I do have my own fears. What if, in a situation where I make myself able, I fail to protect something? What if I can't manage to pull off something I believe I can do, and someone other than myself pays the price? I'm not the type to throw in the towel when things get really bad, as I said, but I'm also able to accept misfortune should it affect me only. If, say, I had a wallet full of cash and my money were to go missing, I wouldn't mind so much. However, if in a similar situation, I were planning on spending that cash for the pleasure of someone close, I'd be annoyed and almost angered. Taken to the extreme, what if I were being assaulted (acceptable), and someone (anyone) is seriously harmed or killed because I was in the wrong place at the wrong time and am unable to help (less than acceptable)? What if I were restrained and had to watch someone be harmed because of my failure (which I mentioned I do not fear)?
What if, for a more practical example, a friend was verbally abused (and hurt) because of something I did with someone else? I would feel angered, which to me is another description of what it's like to want to rebel against the uncontrollable nature of the world's happenings; fear.
