Seems very strange to me that someone would consider a career without an inkling of what it is about. When it was suggested that I became a pharmacist, I also had no notion. I went straight to the local chain (Boots) and asked what I could do. They referred me to the Area Manager who suggested I worked as a Saturday boy at the local branch. That was in 1950, and I worked part time and vacations all through college and that is where I did my intern. No real problem. Do you have Saturday/evening etc people in the US, or does everyone work full six days a week?
