At one point in my life, my greatest ambition was to be a nurse. With green hair. Green was my favorite color, so why not?
Since I was so sure of my future profession, I was super excited for my Kindergarten assignment of drawing what I wanted to be when I grew up. I started right away. I proudly walked my finished creation up to my teacher and expected a gasp of surprise at my artistic abilities, plus a first place finish (though there was no prize).
Instead I got a steely stare. I was promptly told no one had green hair and to do it over. Dreams crushed.
I fully believe some people are made to be teachers: those that inspire and love learning. Then there are those that need to find a new line of work, prison warden perhaps?
