As I type this I am sitting in the University library, 8,134/10,000 words into my dissertation and drinking lots and lots of water to combat my dry lips and my need to fall asleep. (It works, seriously, drink loads and you won't be able to nap 'cause you'll need a wee all the time! Tried and tested essay writing method...!)
Just a short post to provide a small break for my brain (I can knock out a long post in hardly any time, but writing 10000 on the lack of use of autobiographical research methods in Criminology takes a lot, lot, longer) and to give you a little insight into my current life mantra. I keep telling myself this in all aspects of my life at the moment, doing lengths in the pool, writing my essays, trekking up hills.
Whatever you can apply this saying to in your life just remember one thing - never, ever give up.
