I am the player closer to camera (orange shirt). Feeling like there is so much am doing wrong that I do not know what are the few most important things should focus on during the match now. do not have option to train too much (work, 2 kids, a lot of other things going on) so usually just try to improve during the rallies with my friend by thinking on certain things I tried to learn online. But it feels there are so many things it's overwhelming and just slip to the old habits very quickly. Any tips and the most important points that should focus on an improve?
