You can't please all of the people...

so, rather stupidly, I asked two different professors for advice on my prototype PhD proposal. Unfortunately their comments are diametrically opposed ("concentrate on central texts" "choose something obscure rather than a central text which has been overdone" etc etc). Now I'm just confused, wondering perhaps whether my idea was any good in the first place. At least I now know that there is no point writing a proposal to aim to please a panel of people: there will never be unanimity.
