How in hell do you keep your desk that tidy? You must tell me your secret.
Hehe, thanks, I try to keep it clean. Here's a tip (this is what I do):
Anything in your room that you haven't even touched for over a month and probably never will, either get rid of, throw it away, give it away, or put it in storage (the attic, etc.). Keep similar things together and avoid clutter at all costs. Anytime you see stuff stacking up, throw everything into the center of the room, group similar things together, then put it away. Once the clutter and useless stuff is gone, there's less possible things that can find their way onto your desk.
Next, try to keep your desk dedicated to a single cause. If you want to game, do homework, disassemble and repair a phone, and also eat, then do one at a time and make sure you finish before proceeding to the next task. Once you're used to this you can move onto multitasking.
Remember: If you wouldn't want a lady friend to come over and hang out in your room, then something needs to be done.
Best of luck
