That hesitation and "figuring out where to go next" are difficult to overcome.
Get a Dry Erase board or even large sketch tablet and pencil. Doodle one design until you don't even have to think about where you're going next. I do this with every new design I try. I draw it until I can almost do it with my eyes closed. When I sit down to the machine, the mechanics are different, but I don't have that hesitation about where to go next.
