I think the same is true for time. If our days were 30 hours long, would we be any less busy? I’m not so sure. Just like money, the answer for a lack of time isn’t hoping that you will magically get more. It’s using what you have in the most efficient manner.
Here’s a nice article on webworkerdaily.com entitled, "12 ways to find more time." I especially like #4. If you find yourself unable to concentrate on a specific task, move to another. Everyone handles certain tasks better at different times in the day. For example, some people write better in the morning and research better in the afternoon.
It’s all about figuring out how (and when) you work best and organizing your schedule around it.
