I didn't fully understand the premise of this question when I read it last week, but I'm going through a slump in form at the moment and coming off the field yesterday this thread popped into my head.
For me, I knew what the problem was, and I knew what the solution was, I just couldn't put it into practice, so the approach definitely had to be: battle it out. My problem was what
@bk was saying about trying to take in more than one thought. It's a dilemma that you can't think "play with a straight bat" and "move your foot to the pitch of the ball" and "connect under your eyes" all at the same time, however, you do need to do all those things, one or two is not enough. Easy as it is to tell someone "clear your mind and watch the ball, the rest will fall into place", it's not so simple when you know in fact there are three technical things that, if you do them, would work. It's hard not to have them in your mind.
I do know though, that clearing my mind and watching the ball like a hawk is what's going to get me through it, and it's time at the crease that allows me to remember what that feels like. I haven't scored more than 2 runs till yesterday, and I got 9, but that 9 took me 5/6 overs, I remembered what it felt like to see the ball all the way onto the bat, with a clear mind, I got my front foot across to a full half volley, I rocked onto the back foot to defend a short one, I left well outside my off stump, and I believe again. It wasn't a successful innings but I felt closer to getting in that zone where I trust my ability, and my season can finally actually start.
