No, his advice is think about what you really want to do before you go ahead and follow the party line.
You're missing my point. He has admitted that most law students have goals that are different from his goals. The reason why he does things the way he does is because his actions are geared towards his specific goals. However, he is passing off his "specialized" advice relevant to him and others similarly situated as "generally applicable" advice relevant to most students. You don't see a problem with that? And just to clarify, I'm referring to the advice he was giving regarding the topic of this thread, not the advice you're referring to above.
I agree. "Specialized" advice should be marked as such, and no one should start giving us advice if they regard the rest of us as followers. Otherwise, we will do as they say and eventually they will be a part of the "sea," too. Vicious cycle.
But, I must say, we cannot equate 'different' and 'better' because they are simply different.
And, while I see your point about not coming across as a self-absorbed penis by openly offending your classmates, I have to ask, what is the 'difference' between thinking it and saying it? I think most of us can read between the lines well enough. Not that having a high opinion of yourself is bad, but neither is telling people about it. That just makes you a really bad poker player.
