my biggest problem that i work very little every day on my doctorate. I waste my time on nonsense: internet, email etc. I know self will is the key but i need some tips to make me sit on my ass and focus. I don't want to use pills though I can get those legally (I hate them). So give me your best tip to focus and together we will build 10 best tips list. thank you all.

First of all you have to know, that it is important for you! You have to understand that! If it is not, so why did you start to study?
Forget about internet, while you are working. Just google for goot tips. I have already said you about the most important. You have to like your work!!!
