What is the best way to improve?

I have tried many different techniques to try and improve my skills including playing chess everyday and doing puzzels etc.I want to focus on only one technique.Please Help me!!!

54 puzzles and 79 games played won't do much. There is no easy way so keep playing, and keep doing puzzles.

"Keep going, never give up" that's all I can say

Make studies for everything you're doing. The act of creating a study, highlighting patterns, and writing out explanations in your own words will help you internalize and understand everything more deeply than just reading or playing through games. This is something that teachers in all fields have realized. There is an overwhelming amount to learn about chess, so pick something that interests you. A great idea is to make a study of a game you've played and write out notes for all the critical moments, but you could pick an endgame and make a study out of it, an opening that you play, a strategic theme, or just about any book chapter you want to read. It's important that you actually try to understand why something is good or bad and write out an explanation, rather than just looking at the numerical evaluation. Pretend that you're trying to teach it to someone else and all kinds of questions will pop up that you might normally ignore. There's no shortcut but this is a good "single technique" that you can apply to most aspects of your game.

wat does that even mean

@GeorgeZhuang Lichess has a "study" feature that allows you to highlight, annotate, and comment on chess positions. My basic point is that you want your study time to be active and creative rather than passive. When we try to actively create explanations we often realize where our understanding is lacking, and that helps us to improve.

Thanks everyone for your answers except Footballl120:)

If it took only one technique to become better it would be an unrealistic journey
