It doesn't "always hurt" if you just change your perspective. Imagine buying, getting your car, then finding out shortly thereafter that cars with AP hardware are coming off the assembly line at no additional cost. That happened to a lot of us here. There were longs thread here about it that must still exist but are long buried. Basically, like most things in life, we had a choice: complain and cry (or be "always hurt") like the little kid who couldn't enjoy his one cookie if the kid next to him got two, or enjoy what we bought and paid for, and were perfectly fine with, until it cost less, came with more, etc. I took the later perspective and told people to be happy with what they bought and paid for, and never looked back. I was also happy -- not bitter -- for those that got AP hardware and told them so, while telling the complainers to stop complaining.
Life is all about perspective. Being happy and grateful for what you have makes for a better life, at least for me. Being bitter eats at your soul. We talk to ourselves all day long. Telling yourself to be grateful when you tend to feel bitter really works, again at least for me.
