If you like reading, have a look at this blog I follow, where a whole list of excellent reading has been listed, including good fiction, many of which I have read. I learned a lot of new titles of books too so if/when I get back to studies, they are on my list. There are also many more blogs and books suitable for non researchers.
Then, if you are a current PhD student, or even a Masters student, or even just interested in life. I’m almost 100% sure you will find great value in this blog, The Thesis Whisperer.
