If I am being honest, I feel I achieved quite a lot, and learned a huge amount, and really loved my subject.
At the moment I really dont feel it was worth it, due to the very difficult current circumstances I am in. When I finished, I also feel quite removed from other people who do regular jobs (although I have had a nasty wake up call since then), and have felt the sting of others who look down on academic types as living in ivory towers.
But thats just me.
