The usual.
Youre playing speed chess, Youre not going to improve by moving fast. You played a daily game where you played 35 moves in 1 day, and lost.
You can repeat lessons over and over all you want. But as long as you're playing fast, and moving fast none of that is going to help.
BTW i am going through lessons to “relearn” the game and hopefully pick up some new tactics since I mainly learned in elementary school
