I'm trying to contact with a professor from another country to ask him to see my work and send me a feedback. But I don't know what is better to say that, someone told me that I must "sell myself" and tell that Prof. how awesome I'm and someone told me that just be abbreviated and be direct to the subject. I don't know which one of them is correct, I think about that and I'm getting confused; for the first opinion, I think that professor meets many people who are more awesome than me, and he is done of looking for awesome people, instead he is looking on awesome work. And for the second opinion, I think I will make that professor feels in a negative way.
As academics what do you think is the best way for a fresh graduate(Bachelor holder) to contact with a professor who I don't know personally?
