How many psychiatrists does it take to change a lightbulb?
None: it can only change itself.

Extinction usually occurs through failure to change.
Today change is rarely for the benefit of improving everyone's situation...it seems merely to drag all down to a common level of ignorance, dependency and ineptitude.

I have made more than a few mistakes and acknowledge them. I also try to keep an open mind for new evidence which proves me wrong on any issue.

There is a difference between being wrong and not being fully informed. New information requires new conclusions. I once dated a brilliant woman who said "I am never wrong. But when I get new information, or someone provides a better POV based on something I had not thought of, I change."

Think about it.

At work so many people are even afraid to make a decision. If I make a wrong decision I correct it and learned something in the process. Change is inevitable.

We often learn far more from our mistakes than from our successes. Making mistakes isn't a bad thing; refusing to adapt and learn from them is.

I am a stubborn person and needs to be shown another way to do things.

I generally start with plan A, then revise as needed even if it goes to Zed 3 (for you folks in the UK)

I’m constantly trying to change my mind.

Can't argue with that, except to say that in real life when you go down the alternate route, you often find a new alternate appointment which is better than the one you were headed for.
