Now, I disagree with this. In my case, I have a husband who has a good job and a daughter we are responsible for. My husband's job isn't portable, and it pays for medical insurance that we have to have - we have special medical needs.
Even people who aren't married may have perfectly valid reasons for not wanting to relocate. They may be caring for an infirm or elderly parent, or just simply very connected to their friends/family and not want to start over somewhere else.
I have the needs of two people besides myself to consider, and if it came down to it - if going to pharmacy school was going to be extremely disruptive to my family and a hardship - I wouldn't do it. My husband and child are my first, primary and most important committment.
So, no - "going anywhere" isn't always possible, and willingess to do so isn't a good measure of how badly someone wants to be a pharmacist. People have to do what they have to do!
