You know you’ll probably get the lazy answer “play better chess” or some variant of that answer based on how you phrased your question. But create a study program for yourself, start small, keep it fun. For example, try to solve 10 puzzles every day. Play 1 15|10 game a day and analyze it afterwards, identifying your mistakes and recall your thinking when you made them. Try to avoid that type of mistake in the future. Start there, and if you have more time for chess that day, add another chess activity such as read a chess book, or work on a ChessAble course or something. Over time you’ll see improvement.
