In that rating range, the biggest thing that helped me was to remind myself not to play too crazy. People in that range are going to make mistakes and hang pieces. As long as you play solid, you usually don't have to do too much else. Just be ready for your opponent to blunder and afterwards trade into a winning end game. Also, 9/10 you should not sacrifice pieces - most of the time it won't work out for you. So don't do those kind of tactics.

It's mostly about following key principles when playing. That approach helped me reach a 2000+ rating, and I teach others to do the same. You can learn them yourself as well. Here's an example of some chess principles: https://www.chess.com/article/view/principles-of-chess

Getting better at chess.

Using the opening to develop pieces is a big factor.

Follow all principles, dont play blitz, only rapid and youll be in the 4 digit club in no time

At 700-1000 you're still struggling with basic tactics and self control issues.

Work on "sitting on your hands" so you won't play the first move you see but make sure first it's no blunder. Take the time to check and double check on tactics.

Once you're like 1200, endgames, starting with pawns endgames is what you need most.

At about 1600, strategy/mIddlegames along with more advanced endgames (like the hard Rook endgames...).

Roughly.
