Hey Lem,
Ok so I don’t think you need to start completely over again to get rid of this problem. It’s just working on certain areas and analysing your game for what is going wrong which you said you arw doing by watching videos back so that’s great! Often it can be a couple of key things here and there than make the difference with your shots, you’ve already noticed one which is not staying low enough and the other which was blocking rather than a drive or topspin. So focus your training on improving these areas and work on that at the moment. I’m sure with time you’ll get past this frustrating stage which happens to all players at some stage!
Dan 🙂
