Yes you are on the right track.
(Although you WERE asking if you could get into MIT in the first place. If you had asked if you were “on the right track”, it would’ve been a really different thread)
Just a FYI, if you dislike competition, schools like MIT/Harvard aren’t really a good match for your personality. “New England” Ivies value competition highly. If you’re really not a competitive kind of person, try schools like Duke, Notre Dame, Stanford, etc., students there are more chill. Btw though, competitive doesn’t mean not collaborative; uncompetitive doesn’t mean unmotivated.
Also, you said “I thought posting here wild ease my mind and stress.” If you’re looking for pure encouragement, maybe go talk to your friends/counselor, CC is not the right place. People here are usually brutally honest and realistic with you.
