After my ordeal of 2005, I took a look at my life and didn't much like what I was seeing. Too much bitterness, too much negativity, too much not being a nice person. I realized I could not change my past, or the past, but I could change my future.
I changed. There is no reason for it. I realized that when I was negative and sour and mean, it just hurt me, and maybe some others close to me, it helped nothing. I'm still working on it, but the wife often tells me I'm too nice, which is a good thing I think.
We're all mortal. We have a chance to influence and impact others for better or for worse. We can be tempted by "the dark side" to try and pay back others for every small wrong, imagined or real, and spiral down into being a Negative Nancy, and it ends up harming us, not them. My focus each day is to try and smile at strangers and say hello and make people feel valued, or at least noticed positively, whether they are a bum or the janitor or a neighbor or someone I pass while jogging (or they pass me usually).
Be nice to folks. I sometimes get my meanness out on line, but I'm pretty nice in real life. I'm working on the on line part. Just be nice.
