Hi nimrod81 - I appreciate it's not going to pop into my head after 3 weeks of reading, my concern is more centered around the fact that all the other new PhD students seem to have something definite to answer when asked "so what are you doing yours on??", Whereas I just stutter and flounder for a good while and feel/look stupid... then tell myself that I really have no clue what the answer to that is. So in those respects, I suppose my point is that I wonder whether I should have at least some 'clearer' ideas of what I am doing.
