Go Back or Not to Go Back – That is the Question

I have begun to seriously think about heading back to school. . .again. In 2006, I received my Master's in Management which was done completely online. I have begun to think about how I can expand my experiential learning and for me I can do that best through educational pursuits.

So. . .I have two options:

1) Pursue a 2nd Master's in Industrial & Organizational Psychology

or

2) Pursue a Ph.D in Industrial & Organizational Psychology

The latter option would fulfill two goals for me – a second advanced degree and a doctorate. Not sure what I might do, but if I do anything it will probably come middle of 2008.
