To improve you have to take some of the above critics at their word and face-value, I do not believe any of them are accusing you of being either bad or great at chess, thay are just suggesting, from veiwing your games what seems to be leaks or holes. What you suggest is somewhat true the game of a 2000+ and a 1500 or the game of a 1500 and a 1100 are not too dis-simular, the board and the pieces are the same, however the higher ranked player make fewer errors, and 90% of this is concentrated in the openings and the structure created and maintained through the middle-game, countering threats, improving your worst piece, pressuring your opponent to give you an extra tempo etc., I would suggest study or an hour or so, by veiwing a masters game, chess mentor (on chess.com) and some other puzzles for fun, and then play a game and try to execute that opening, then win, lose or draw, analyse that game, total time around two hours start to finish, so maybe only 2 or 3 games a week, but slow and steady improvements until you can mix up the balance of study and games to suit, good luck.
Stuck at a low level????????/

Is it just me or am I stuck at 1000 level because most people are pretty good? I don't exactly suck at chess, but I know I am rated higher than this in reality. It seems that there are a ton of 1500 level players stuck at 900-1000 because we keep playing each other. I would like to play someone rated 2000, because I think it would be fun, and very surprising when the lower level people win.
I sometimes watch the 2000 level players play, and they do not seem all that great. Is there anyone else who feels this way?

I would say there are different issues the players face at different rating levels having climbed the rating ladder my self. and fallen off the rating ladder lol.
I put together a guide here check it out: https://www.chess.com/forum/view/chess-players/from-a-500-elo-beginner-to-a-2000-elo-expert

2000s are nothing special but you need tons of practice to reach their level. You may have watched a few games where they didn't play on the level on which they usually play so you thought they were worse then they really are. 2000s still make basic mistakes that's why I beat 3 of them on this website. 2000s almost never make one move blunders (unless they are in time trouble), 1000 rated players make them in every other game. 2000s rarely make simple tactic blunders, 1000 rated players make those kinds of blunders all the time. 2000s play way better positionally then 1000 players. If you played a 2000 player you would lose 20 times in a row.

ive been stuck on 300 - 350 lately, any tips?
work on your tactical ability, you can do this by doing chess puzzles. This will help you see the board better and reduce the amount of pieces you hang. another thing that could greatly help you is learning opening principles. you don't need to learn any thoery of an opening, just the general principals on how to start a game of chess.

You might want to stop bringing your queen out on move two. That quick checkmate idea will rarely work on anyone who is 500+.

just got a quick win, 6 moves on a 350
thats great, how did you improve from that game?
