The 7 Habits of Highly Effective People who are Linux Users
1. Never login as root - This is redundant if you are using a Linux distribution such as Ubuntu which uses sudo to elevate a user temporarily to super user mode. Nevertheless a valid point.
2. Properly name your files - I usually stick with that but even if you have spaces in the names of your files, bash completion helps you in getting the names of the files right.
3. Place /home in its own partition - I concur with that wholeheartedly. Read this article to know more about partitions.
4. Proper crash management - Use xkill and the likes to close a misbehaving application.
5. Try out multiple distributions - You have got a whole lot of them to choose from.
6. Brush up your command line skills - Learn to use command line tools to accomplish complex tasks. It is a big time saver. Don't forget to pick up some bash scripting skills on the way.
7. And finally, always be ready to unleash the power within - in other words experiment.
