> I mean, if you changed your future intentionally, it stands to reason that you would have felt comfortable that any adjustment would be better than what you have.

The problem is that you don’t know how things work out, because any small change can lead to large unintended consequences.

Say you always wanted to be a doctor, but a troubled home life made you choose the fastest path out of your house, so you ended up in some dead end desk job adjacent to the medical field, but nothing like how you imagined.

So you decide to go back in time, and through whatever method, convince your younger self to fight for your dream job and do whatever it takes to go to med school, because it has to be better than the life you have now.

So you go back to “your” present, only to find out that present you failed out of med school because you buckled under the pressure and became an alcoholic, just like your dad. So now not only are you stuck working some dead end job, you’re an alcoholic to boot.

I know this is just an example, and it’s easy to say “yeah, but that’s just one very unlikely case.” But the point is people don’t know what bad consequences might come with your changes. People only ever focus on the good.

Another example is, you go back in time because you decided to take that job in a nearby country/state that you turned down all those years ago. Present you: You’re happy with your job, you met a partner and had some kids, life’s great. Except for the fact that 3 years after you moved there your parents died in a car accident on their way to see you. If you hadn’t changed history to make it so you moved there, they wouldn’t have needed to make that drive, and they wouldn’t have been at that exact place at that exact time, and they would have been fine.
