Hey Joe,

yeah, the standard answer is practice, practice, practice, eventually you will find your method. It's kinda boring practicing one chord shape over and over but that's what it is I'm afraid. Maybe 5 mins per day on the C then move on to other shapes.

try to incorporate finding and playing other CM chord shapes over the neck so you learn while you burn and don't get bored. Boredom is the killer so keep it interesting for yourself..

That's probably what you already know but hope it helps ya brother..
