Thanks for the helpful thoughts. I have to defend my dissertation in five months but i feel i am nowhere with lots of paradoxical sets of data and theories in my mind. The most difficult part is that i am writing this social science thesis in English as my second language. I am not confident at all about the clarity and meaningfulness of my writing. It is frustrating and takes huge time and energy to focus on my subject and at the same time avoid any ambiguity in my writing. Any comments or thoughts how i can manage such chaotic situation?
