Ha, ha. I've just been looking through stuff that I did when I started (last century it feels like) and I've just read my first literature review. It's cr*p! Oh well, at least I can see that what I am writing now might actually be quite good.

At the end of each year of PhD we had to do a mini write up and one of the things I did in my first year was quite a comprehensive lit review. By the time I came to my third year I, like you, looked at it and thought - who on earth wrote this rubbish? Oh, I did?!?!?

The only good thing was it meant all my references used then were at least already in my database!

And it's a good thing definitely realising how you are improving!
