You didn't change your mind. You got scared

Then you start collecting evidence. Someone tried it and failed. Someone moved abroad and came back. Someone changed careers and earned less. Someone opened a business and discovered that customers don't give a shit about a founder's enthusiasm. All useful information. What interests me is how quickly you stop looking once you've found a reason to stay where you are. You don't ask what went wrong, which conditions were different, or what a smaller attempt would cost. You've found the corpse you needed. Investigation complete.
