When making a mostly emotional decision, it's pretty common for our brains to tackle it logically, and our guts make a decision while our logical minds are still arguing pros and cons. And it can be surprisingly hard to tell when this has happened. Fortunately, a coin flip can easily tell when it has - just don't take its word for anything! Instead of doing whatever it says, pay attention to your own reactions. If you have mixed feelings, you're genuinely still divided; if you're either relieved or disappointed, you've already decided and can take action accordingly.
Note 1: this is NOT for when you want one thing but need to talk yourself out of it (e.g. breakups). Note 2: also obviously not for when there IS a logical answer that's just hard to admit (e.g. the awesome house is out of your price range).
Good luck all.
