Good advice from Edge
@DorsetDan try to stick to a few shots you are comfortable with even if it is the massive forward block
There's quite a few of us not not done so well this year so I wouldn't fret too much, in 2015 I couldn't hit a cows (No Swearing Please) with a banjo and I've got 18000 runs for my club...not quite as impressive as it sounds I've played a lot of games!
Your answer probably lies in more practice as it does for most of us. In the short term I would be one thing(this is what I'm going to do from here on in)
Really really watch the ball from the bowlers hand onto the bat. However you get out and whatever score you do or don't get don't let it be because you have not made an extra effort.
So at the end of the match make sure you walk away knowing that.
It's not rocket science game changing wisdom, it's very simple.
Good luck, one helluva lot of us all in the same boat, it's crowded
