This is quite an interesting topic, I am still sort of torn by not going into practice cos 2 of my professors have asked me to do a Ph.D and consider academics, but I dont know if I could get into that all my life ... its not a money thing (one of the ones who asked me also works for Baker and McKenzie and earns a shed load), but somehow the idea of teaching and academic research for the rest of my life doens't really appeal.
But if there was something I wish I hadknown it is this: I wish I had known how boring criminal law was, it all looked so interesting to start out with!
