I loved school while I was there. So I didn't feel like attending was missing out on other things.

Now the opportunity cost is sufficiently high that I'd rather do other things, but still. No regrets for me for my years of post-graduate education.

My years in grad school were some of my happiest years. I would go back again if it didn't mean forgoing the ability to ever retire.

Depends on what you want to do if you had enough time and money to do anything. Imwould spend time learning and discovering things.

I was so happy in grad school. Got my first real paying job when i was almost 30. It worked out well for me. I was damn slow to finish that damn diss, but now I'm on top of the world. :-) Everyone has a different path in life.
