The quickest way to improve at chess is to actually commit time to studying the game and practicing tactics. You can study the game via instructional videos, books, lessons, tutors, etc. The more you are exposed to high level players and high level ideas, the better you will get at implementing what you see into your own games. For example, if you are having trouble making it out of the opening with a decent position, you should spend some time looking for an opening that suits your personal taste and playstyle and studying that opening you enjoy.
Tactics are also incredible at opening your eyes to winning combinations that could show up in your games. Essentially, tactics are combinations of forcing moves that result in a winning position for you. Forcing moves are inherently more powerful because they cannot be prevented or defended. Tactics can be practiced on various apps, including Chess.com, in the forms of puzzles.
Overall, study and practice will do much more for your personal growth as a player than sitting down and playing 10 matches of blitz. If you are looking to improve, practice more, play a little less, and analyze your own games to see where you went wrong or can improve.
