Whenever I have to hammer a nail into something (the wall for a picture mount, a piece of wood for a project, etc.), I hurt my fingers when I slam the hammer against the nail. Even when I don't hit my fingers, I'm scared that I will.
I've tried being more careful by not slamming as hard and not starting back as far, but when I do that, it is much less effective and takes longer.
Are there any effective, yet safe ways to hammer nails into walls or pieces of wood, etc.?
