I have an agreement with my thesis advisor in which I will send him many emails as I think through an issue, and he doesn't have to read them carefully (or at all). I will clearly mark the parts that he needs to answer (like the time of the next meeting or other silly things), and if I do need an answer to a question I might send an email just with it. Then, when it is time for us to meet, all that writing has helped the ideas solidify in my head enough for it to be very easy to explain to him what I'm trying to doand how, and then his comments can be very useful. Before we arranged this I'd block for days without managing to think some detail through, but now I just start writing him an email about the issue and by the end of the email I usually have an idea as to how can I solve it.
