Tip #7: Back up your computer/important files regularly (you should do this even if you are not writing a thesis). Do not believe your friends and family when they tell you that you are acting paranoid because you have your data on 3-4 computers and 2 of them are backed up on external drives... and they are in 2-3 different locations for extra security against fire and theft.
As a side note, I personally have most of my stuff in this situation. There are a few things that are on one computer only and may not be backed up - this scares me and I will remedy it soon... But I'm not paranoid... seriously... I just back up my own computer and my supervisor backs up the lab computers... Well okay, I look paranoid but I don't feel paranoid... It is 2 years worth of work and worth a degree! Okay, I'm a little paranoid but I maintain that it is a normal level of paranoia...
The above picture was taken from the airplane on my way home from Kelowna earlier last month. If you look closely you can see the Rocky Mountains peaking through the breaks in the clouds.
PS: GO ITALY! The 2008 EuroCup (soccer) quarter finals are today.
