OK, this Monday (yesterday) sucked so much. As I worked all weekend (including the nights) on my thesis, I was in a bad mood and some things that happened around made me really upset.
At least, the day ended with a long phone call to a friend of mine :)
Tuesday was much better: I WILL finish my thesis today, there are only a few corrections left (and there is already a beer in the fridge to celebrate this great moment). Furthermore, I surprised my supervisor today by being way ahead with my work. Good to hear a "good work"! Same seems to be true for my thesis so far.
