Yep - everyone has that.
Back in my Army days they used to teach a concept called the "decision cycle". In a nutshell it is 1) Identify the objective 2) Develop a plan 3)Implement the plan. I'm sure something similar to that is still taught today.
For PzC, the first thing I always look at when starting a game is the VP levels & the objective hexes. That should be your primary concern when playing. Once you do that you can devise a plan to achieve those objectives & a victory.
From the example you provide, I'd identify the weakest point in the line (the Hungarians) and mass all that I could against that point while leaving a screening force opposite the well-dug-in Germans. You have some heavy artillery - use that first aginst the point you want to attack & try to disrupt those units. Once that is achieved assault those disrupted unit(s) to open a hole in the line. If you have mobile units, keep them close by to exploit your breakthrough otherwise keep some infantry available to do that. I've found that it helps to "think like a Russian" in the east front games. IMO, PzC is designed just for that.
Of course, all this is easier said than done so Good Luck!
