Why am i so bad at chess 😭

Hi there,
I am rated over 2400 online (https://www.chess.com/member/ppandachess). I created a free course that will teach you a training plan to improve. Feel free to check it out: https://www.panda-chess.com/daily-improvement-plan
I think that my free training plan can help you.
I also offer private lessons: https://www.panda-chess.com/private-coaching

To get to 1000, it's mainly about applying solid (opening) principles and not blundering. Learn an opening for white, one for black, develop your pieces towards the center, castle and make solid moves. Learn something about tactics and try to look for them in your games.

Learn openings don’t blunder pieces know how to spot weaknesses in your opponents position study endgames train tactics and don’t make bad positional decisions. Thats basically a 2200 online 10 min player.
I am just stuck at 800-908 I just can’t get to 1000 why I have done so many tactics, I don’t know what to do Opening traps, don’t work, why?
