I need some opinions on my story. So, I was admitted to one of the top grad schools Europe. I only applied for for this one. I was already going to a top 5 school (usually rank #1 or #2 in the field) in the US. I just got one credit for a class (got an A). For undergrad, I was admitted to one school I applied to, which was one of the better US state schools (maybe just above average overall), with bunch of my friends and their friends and we all connected. For high school, I was admitted to one, lottery-only public school, one of the better ones in the city, which was the only school I applied to. This one was probably the riskiest. For middle school, I came into the US with pretty much no English. Basically, I apply to one place that I thought was the best choice at the time. Obviously, I changed my mind about the top 5 grad school so I applied elsewhere, which I now think is my best choice. It's not because it was such a competitive environment to stress me out, but I just dislike living in this city, though I think I prefer to just generalize and say living in the US. Personally, I don't understand why I do this or perhaps do this to myself. I only heard one person's opinions for each of the process and would constantly repeat that going all-in in one place is a bad idea. I'm pretty sure I see the logic behind on why, but I don't understand why I don't carry out the logic into actions. Does anybody else do this? Is there some name for this syndrome? Can you conjure a hypothesis on why one would do such things?
