1. I'm in grad school now. I like going to school and my workplace is paying for my classes. It will help in my career choice, but it won't provide me with advancement. It will just enhance the skills I already have, which I suppose is a benefit for me and my workplace. I have always been in some sort of class or another most of my life. I jump at the chance to start a new class. 2. Not until my 40's. 3. I think a good reason to go to grad school is simply the desire to learn. Or, because it's required for your field. 4. Not for the paycheck. 5. Best state of mind? Interest. Be intensely interested in your chosen field of study and enjoy yourself, regardless of what you might think you will do with the degree. 6. I looked for the ability to take online courses, as well as the ability to spread the degree out over a long period of time. 7. I work full time and take one grad class at a time. I would love to quit work to go full time, but...life, and all. Good luck. :)
