thesis

It happened to my Masters thesis and I think it's happening to my PhD too. Basically, in my Masters I ended up working on what I had initially thought was the most difficult part. Now for my PhD I am reading Information Theory! For God's sake, Shannon wrote that stuff and he was the last to understand it. I have done some reading in this field before and I had found it DIFFICULT and now the course of life has lead me to it again ... what am I to do? You would think that when you are free to pick your topic you'd choose to work on something that's easy and understandable to you, not something you have to work your brain to pieces on!
