I suck
Your puzzle record is good. You don't suck. There is no benefit in trying to solve puzzles quickly. Chess.com only gives +5 for each puzzle solved. So, take a bit of time to carefully evaluate possible tactics. For example, I solved the last puzzle that you got wrong because you missed the tactic of deflecting the opponent King by recapturing the Queen which allows a fork by the Knight that captures the Rook in the corner. Get better at spotting tactics like that.
