What’s your go-to swing thought?

I’ve been playing golf for 30 years, and fluctuated between 2 and 6 handicap after I “peaked” but I still have a tendency to lift my head during the swing. My miss is usually a push and sometimes a thin shot which correlates with getting too far on the left side before impact. I have to often remind myself “keep your head down.” I think part of the problem has been that I have a really large shoulder turn that causes me to strain to keep my eye on the ball at the top of my swing if I raise up during the swing. Reminding myself to keep my head down forces me to rotate more on my spine angle which makes it less likely that my head will struggle to stay down during the backswing and the downswing. I also tend to struggle more with longer clubs because my spine angle is more upright which increases the risk of my shoulder turn pulling my head or of the way.

I’m genuinely interested in what others’ swing thoughts are that might be beneficial.
