Msc Thesis: Drowning in knowledge and ideas, whilst my supervisor is not answering my emails I am a student at Cybersecurity master's degree program in a Greek University and I choose as my topic on "Multiparty chat privacy protection mechanisms" my idea behind this was that I wanted to implement on a post-master's time a system so a Bibliographic Research on that topic would provide me this knowledge.

So I started doing that and I found myself bombarded with new ideas and approaches for the Msc Thesis while I became more knowledgeable about the technologies on this topic. Therefore I discussed my approaches with my supervisor and came up with one approach. I followed that one but suddenly I became stuck and I see time slowly ticking towards to the end (It is far away but I do not want  my work to become last-breath patchwork).

Therefore I contacted with my supervisor via email and to make up with time started to work on a second approach. And here's the problem:


I sent 3 emails towards him and still no response. (I sent 1 email every 3 days in order not to fill it with spam and being way too pushy/impolite.)
I find myself drowned and with an unmanageable heap of ideas.
I do not feel confident I can manage in time at least one of the 2 approaches.


In other words I feel drowned with knowledge, stuck on an unmanageable heap of ideas and alone whilst I work on my MSc Thesis. How do you suggest to manage that?

Ps. On of the 3 emails I sent towards him is a physical face-to-face request and I have no other means of contacting him.

An approach to fix that is to ask for external help/counseling regarding this issue. But would that be offensive/rude towards him. Also my first email is at 29th of October and the last one 1 day before posting this question.
You don't have to arrange a face-to-face meeting to meet your advisor face-to-face. Just go to his office when he's in and knock. Start with "Are you free?" If he says yes, you're gold. If he says no, ask him when you can come back.

It might sound pushy, but if you're not making progress at all, you're wasting time. Your time may not be as precious as his time, but it's still precious. Don't rely on email; arrange a meeting.
