People have the equipment thing down, and the separate office thing has been mentioned already so I'll try to add something new.

Open up your /etc/hosts file, think of EVERY website that's not work-related that you visit regularly. And redirect it to 127.0.0.1.

Once you get working, you'll forget its there... but especially if you use this computer for non-work things, it can be hard to get the engine started.

Another thing, I dual boot my computer. Windows for fun, linux for work.
