How do I distinguish between a genuine goal and changing a circumstance?

I’m double diamond but still find it hard to distinguish when I’m changing the circumstance vs setting a legit goal. For instance, I have a goal to move house. I like my reasons. But ultimately I believe I’ll be happier in a different house. Does this suggest I need to do more work where I am? Or is liking my reasons enough to leave?

I really want to understand better when it makes sense to change the C.
