A form of "analysis paralysis" I see my adult drawing students commonly put themselves through is the idea that they have to get something drawn correctly the first time they draw it. This drive for perfection straight out of the gate is horrible for our self-esteem, especially when we're faced with a task we have not yet mastered! I often remind students that they don't know how to imagine the perfect drawing in their head because they have to use their fine motor skills to actually execute the drawing. Fine motor skills are a factor within their control, but more often than not those skills are underdeveloped in adulthood. Because of that, the moving of the hand is a game changer- you can't just "picture it" and be done! And if you're like most of us, you need to be prepared for making adjustments.
