I'm with Rick, and usually to an extreme level.

I think I think too much.
I know what I want(from a scene) or have thought of a particular way to capture it, and if the light is not as I wanted it to be, I don't bother, even though the light may be OK.

I think I need to plan, and/or expect just a little less from a place, and just try to get more out of what's there when I get there.

Other issues I have is which way did I just come from, and which way do I want to go back(I usually vary it just for the sake of variety). I know what's back there and there's definitely a scene to capture at a particular time of day, but I think about the unknown alternatives in coming home a different way.
Usually I'll regret it, although occasionally it works out too.

planning is good, and helps to get the best outcome out of a spot, but being overly fussy sometimes is a drawback too.

That's landscapes.. all other forms of photography I just spray and pray
