Hi Argh, hmmm, it feels strange to call someone by a name that is more of an angst-noise. Firstly, you will never feel that you are 'doing enough' so I think that on a certain level you just have to accept that. I think if you are trying to get a handle on your literature review you are doing pretty well. This is the year to read read read. And of course you can read 'critically' right from the beginning. You'll probably find that your critical faculty will improve as you become comfortable with a broader mass of material. If you can start to draw up a broad overview for your thesis soon this will definitely help for the months and years ahead, and it can always be modified as you go along. Try not to worry, allow youself to get to grips with your material and your project and enjoy your first year
