why don't you start by setting small goals for yourself. one half to an hour a day of working on writing the thesis. or at least writing note cards of what you would want to put into the thesis. a half hour sounds like a good start, the more cards you write and more involved you become the more time you will likely spend on it. you don't even have to do it in any particular order. just write ideas down on the cards as they come to you. sentences. paragraphs. you can organize them into categories later. who cares if you throw half the cards away when you are done. the idea is just to start writing and getting those thoughts down. take care.
