Forever 400?

Recently, after a long hiatus, I decided to play chess again. While I know my account says I have been on chess.com for 2 years I really only play for like a week before that frustration sets in of constantly getting stomped on. This time, I want things different; I have resolved myself to not suck. But how?

I lose for the stupidest reasons. There is always something I don't look at and by the time I find it it's too late and I lose. Even when I have a good position (in my mind anyway) I simply just don't know how to attack. I also notice that I make a move thinking it'll be good, but about 5 moves down I'll realize I'm trapped, or I'm in an unfavorable position, or that previous move left something undefended and now there is a queen in the back ravaging my king side like a medieval English village.

I realize openings aren't important. I don't know what the Sicilian opening is and I'm pretty certain my opponent doesn't either, so the problem has to be the part where there is no opening, no book, just strategy. The question is how. How do I improve? What pointers can be given to me?

Honestly, the only way I think you should try to improve is by playing a ton of games. Ofcourse, you should be looking at your games, but more importantly you need to be playing over and over and over again.

What happens is you develop positions of the board you've seen before. Trying playing the 1st move of the game every time. Don't switch it up. As white, maybe play e4 or d4 or c4. But choose one and stick to it. Try to set up the same moves and take subtle mental notes of common blunders.

Develop your pieces, take control of the center, and simply think before you play. If you simply don't give you're opponent a piece for free in one move I promise you're rating will sky rocket by atleast 500

1. Adjust your live settings so that you are only playing +-25 opponents.

2. Relax.

3. Play the bots (between your rating and double of it.

4. Do the puzzles.
