Where do you pick?

Curious where the different sweet spots are people like to pick. I know a lot of threads have different places but thought we could all list it out so everyone can see in one thread. Also do you dig down to the blood or just the top layer of skin? I try not to hit blood but sometimes it happens. For me there are 3 spots: 1&2. in the fold of the knuckle of my thumb and big toe on the palm side about the size of a quarter. 3. Palm side area between the pinky finger and hand about the size of a quarter
