Quote From Teaddict:
Thank you for the advice chickpea. I do like the idea of creating summaries, I think they might be very useful. The literature review, drafted in the first year, might also be useful in piecing together the literature, even if you don't actually use that particular literature review.
The majority of my writing from my 1st year literature review made it into my final thesis, so it is well worth writing it as though it will be included. I used Endnote and used my own keyword system to track my papers. I wrote a paragraph summary of everything I read and put that into Endnote too so that I could easily track the arguments.
I'd also second the My Tomatoes tip mentioned above to make sure you get good use out of your time. Go to all the training you can, and make connections with people in your university and beyond.
Final point would be to make sure you take breaks, during the day but also keep time for yourself and hobbies, friends etc. Don't try to do too much at the beginning, it's a marathon not a sprint. There will be points when you lost motivation and you need to be able to spur yourself on and push on.
Good luck!
