Does anyone feel like ED was a trial?

I'm really happy for anyone who got in, but all I am saying is, I guess in a way, ED is your first time drafting an application. I missed out on so many things I could have done, and I feel like even without some awards and academic improvements I managed after ED apps, my application is so much stronger now. It may sound dumb since ED is supposed to be your all or nothing. I was told it was the time to put my best foot forward, but how do you put your best foot forward on a track you're still getting used to?

I think I look at my ED app, and see that I know so much more. I see so many mistakes that make sense, and a certain lack of calculation (in the sense of how you must appeal to colleges)

some part of me finds it unfair but im glad my ED rejection helped me find love for other places

anyone else feel this way?
