Improve chess game

Hi guys, I'm pretty new here, I've been playing chess since last week and I just felt in love with it, it's like an addiction lol.
I wanted to ask you guys some ways to improve my chess games, I can't get above a certain level or figure out some good moves, youtube videos are not enough, practice? a coach? book? what did you do to get better? thanks in advance

Well, there is a book called "Bobby Fischer Teaches Chess". I improved a lot in chess to turn into an Intermediate player from a table top beginner player because of this book. I hope I wrote the book's name right.

By the way now I watch youtube videos for improvement. They are helping me to learn new openings, develop some strategies.

I am not a genius as I said i am intermediate, but I like to share what I learn. So, I also opened a chess channel in youtube. Pls support me by subbing the channel. Its called Arunabh FX.

If you want to improve and are a complete beginner, there are two things you should do:

1) Play a lot of classical games (and afterwards analyse them, especially your mistakes)

2) Solve tactical puzzles, here on lichess or on other websites (I personnally prefer chesstempo.com for that in particular). Take all the time you need to find the answers. Solve 5 puzzles a day, or as many as you want

Do that during several months, and then when you feel that you've improved and you don't blunder pieces in every game, you can begin to learn other stuff, like strategy, endgame...

In the process, try not to play too many blitz and bullet games.

Enjoy!
