My game against strauss42: How stubborn thoughts create blindspots

Time control is 45|45. I won a piece early and was quite happy. Though I felt uncomfortable the whole game because of the enormous initiative that white got in return: a knight outpost, blockading a pawn that cramps my development, and losing a center pawn. At various points, I had a chance to trade queens and make life much easier. But who wants to trade queens and go into a boring game?!
Well, I should have known better. Please let me know your thoughts. None of my variations were checked by engines, and they usually are not, so I'm sure I can benefit from feedback.
