You can improve by creating a study program that works for your specific schedule and needs. Start small, add more if able. You begin by focusing on fundamentals, which I’m still doing, and increasing the depth of studies over time. For example, solve 10 puzzles every day and review any missed ones until you thoroughly understand why you missed it. Play a game, preferably 15|10 or longer, and analyze it afterwards. Even better, record the types of mistakes you made and keep a log of them. Over time, you’ll notice trends in your mistakes, hey! Now you know what to focus studying to fix those. Work on a Chess.com or ChessAble interactive lesson, maybe rook endgames, or an opening you want to learn better. Whatever program you create, make it enjoyable, not a chore- this is a game after all! Plus by keeping it fun, you’ll likely stick with it and make better progress.
Think about this, if you learned one new chess concept a day, imagine how your chess skill would be a year or two from now? Have fun!
