It feels as though I am pointing at the target, my feet and my shoulders. It's only afterwards that I realise I am pointing right, always right. It's a bit of tiredness, not concentrating etc. Not taking the care to make sure I am actually pointing the right way, not going off my eye alone.Not taking the mick but I'm wondering how that's possible - surely when you glance at the target before striking it you're practically looking over your left shoulder? My pre-shot routine starts with me looking from directly behind the ball up towards the target so I get an idea of what the line is. You could try that and maybe pick a point on that line a yard or two in front of the ball to line up to when you step in? For me it helps that I mostly fade everything so I'm typically aligning five to ten yards left of target depending on the length of club - so I don't feel like it has to be exact.
I'm not alone in doing this, I see it with other golfers that I play with. Not all the time, but it is not uncommon.
