This topic may seem very close to Unable to defend and graduate because of advisers fickle mentality.
I am a Masters thesis student, and been doing my research for nearly 3 years now. Which I assume is quite long for Masters. So why such a long time. Well my adviser ( caring and supportive ) doesn't stick to or follow/have a structure for the thesis. Its like wandering about and finally OK yeah lets do this. Sometimes I face problems midway because we dint plan the thesis properly before hand and foresee what issues we could or would have to tackle way down the thesis, in which case it can be called more structured. Adding to this he is never present when needed.
In-spite of all these, I have somehow reached the very final stages of my thesis and trying to get some good results. I would like to open up and talk to him frankly and still maintain a good rapport so that I can ask to help me publish a paper/journal.
Could someone please give me a template of how I should approach him politely and convey my situation and get the best of this.
