Establish a home for your things.

When you create a "home" for each of your belongings, there is never a struggle to locate it. Once you use it, be sure to put it back in its place, and you'll be set.

Less is more.

Everyone has heard this phrase before, but try applying it to your daily living/workspace. When you have less, you feel less burdened because there isn't as much to keep track of.

The payoff for having less is that you actually feel like you have more... you are not wasting it looking for items or shuffling through papers. You just feel better about your space and don't feel like your belongings own you, but rather you own them.
