besides the fact that forums are a good source of information, I am always surprised that this kind of question is not answered by a simple google search
www.google.com/search?client=firefox-b-d&q=how+do+i+get+good+at+chessSince a long time, we always make about the same answers
everyone has their own advice on this or that book, on an opening that would be better than another, on the tactics (wood pecker or not ?), on what to work on first on the best youtube channel...
in fact each case is particular and I am not sure that the author of the question has his answer, especially since sometimes his level is often satisfactory. But sometimes I have the impression that he is looking for a miracle solution (like : you work this technic 10 minutes a day and you will win 100 elo in 1 month)
we are all chess players with our own background, we are not all coaches
to be good is only a long way.
