After graduating university Summa Cum Laude in Music/Child Development, I continued studies for 2 years to get my Montessori certification. In other words, I was NOT uneducated.
I loved applying the Montessori method, I was so curious as to whether it worked or not. (I found it does, when done correctly)
My boss, the owner of the M. School, perceived that I was passionate. She paid me next to nothing.
When asked "why did you leave teaching?", I always reply, I couldn't afford it.
