There's nothing wrong with change per se either, I'll concede. Still, that being the case, why do it at all? is a fair question to ask.
Expand your horizons, perhaps? Well, what if the horizon isn't all that clear? Besides, it becomes fair to ask in answer to that, what's wrong with I'm doing now? I realize that either question calls for a certain amount of extrapolation, as it's ultimately all in the details. But remember the question is, why change simply to change?
When we took the kids out for ice cream I almost always got black cherry. Why? Because I like it. Why try something new when you can get what you know you like?
Am I being obstinate? Perhaps; but aren't you being equally obstinate in ordering me to change? I mean, what's it to you? It's not like I'm doing anything immoral (on the ice cream question, of course). Further, as I have the right in that sphere to order what I want, what argument can you possibly have against me?
It might be nice to change. Okay, but it might be nice to get what I want too. It's almost a moral wash; wait, no it isn't. It's my right to do what I want among legitimate moral choices. What you think I should do merits nothing for your position. It's only you being bossy.
Maybe I should have labeled this becoming a curmudgeon to the nth degreee. But so be it. Leave me alone where I've the right be left alone; that's all I ask.
