NERD
This is a stock picture on our fridge. I used to love pencils. Then I moved on to mechanical pencils. Then I stopped using any writing implement that could be erased with rubber.
So my degree of perfectionism used to soar to such unbelievable (thereby irrational) levels, that I would write entire essays in pencil first, go over every single curve of the letters in ink, and then erase the pencil marks underneath. Smudges? Start over.
