Save your work in Microsoft's Office applications (word, excell etc.) every few minutes and every time you finish a paragraph. You don't want to write a 1000 idea of yours just to get it wasted for nothing because you accidently pressed at the final moment "No".

also, make a few copies of you files. Sometiems you forget what you wrote as a name for a file, and start a new file with the same name and accidently overwrite that old file. which happened to me once...

always take off your speakers and screen power off. Save energy and be green. Yes, it might be a little bit of electricity, but it's still something, right?
Same thing goes for light in your room.

I think that's enough for now, hope it counts.
