Slowly "progressing"

Even though there is a lot of time left before I need to finish writing my master thesis I am worried. The time is flying, some days I am working more, some less and then there are days in which I feel that I am just reading without any clear view of what I am looking for or why I am reading that specific book or article. I guess it is all part of the process of writing a thesis. I need to be more patient...
