I’m sure no one cares but I got my rapid rating to 300



stop, I am more than twice your rating and I'm not going to call OP trash

If that's a new high, then congrats! Always a good thing and in my experience, progress is fun at any level.
Some thoughts if you do care about progressing further: I do think at your level it is very helpful to work on eliminating blunders. I have a friend who's a bit higher than you, but also beginner level, and working through some GM's advice on how to avoid blunders helped him a lot. Also, I notice you play frequently, which probably means you enjoy chess ; make sure you also allocate some time to studying/reviewing as well.
Anyway, congrats, rating peaks are always fun

.....good for you?
Yeah, people just won't stop telling others how much better they (think they) are, I guess. (Your account is like more than 1 year older, just saying).
Puzzles do help a lot, I will say. Especially if you really take your time to think through them. Which I must say, I'm at times lazy to do, lol....sometimes it's fun to just do puzzles for fun. But the times when I really think through them are, I feel, definitely the most productive. They are, in my experience, both transformative and very interesting too, some really neat patterns and ideas. That said, they also differ from a game setting -- it's also important to train good habits in games so you can find the right moves when the time comes in a game.
