How do I convince myself there’s no alternative universe?

Well actually I know it already, but cant help wondering. I made a poor job related decision and have ended up in a worse role and substantially less well off financially. I can’t reverse the decision as someone else in the role I declined. I can’t help thinking about it and the £ lost. How can I move on?

Obviously, you need to re-look at your career and see what you can achieve now

Meanwhile, I am absolutely baffled as to why somebody would phrase this type of question this way…. Which leads me to wonder if this is another AI experiment thread.
