What are the efficient ways of getting organized? Is there a general principle? I've known for a while I'm messy and disorganized, but it's time to do something about it.

Need advice.

Areas i would like to work on: Work (more specifically work desk and draws, although this is probably the neatest in general) Home desk, home cupboards, wardrobe.

I figured if i can organize all this better, i can start steam rolling into other areas. Any advice regarding will be much appreciated. Thanks.
