Here's one very simple yet potentially lifechanging advice I first heard from Brian Tracy.   1    Instead use that hour to read books that could improve your life.

If you're in sales, Google or browse Amazon for what other people think are the best and most useful books on improving your sales.

    2      . Maybe you want to improve your health, become a more energetic person with a better looking body. Or maybe you want to improve your productivity, your relations or perhaps do some general personal development.

One hour a day is not much. But if you read for one hour a day on weekdays, that's about 260 hours a year.   3    If applied everyone knows what great things and feelings could come into your life this year.

Also, all that cool information and useful advice will start to open up your mind. You will start to see more possibilities in your everyday life.

1. I really don't have the money...

Answer: Visit your local library or search their database if they got a website. Or look for used copies in places like amazon.com or some more local alternative if you're outside of the US.

2. Yeah, ok, but I really don't have the time...

Answer: Buy the books as audio books and listen to them in the car while driving to and from work. Or transfer them to your mp3-player and listen while riding your bike/bus to work or school. Recently selling audio books directly through mp3-downloads have become popular. It's probably something we will see more and more as people and companies discover this easy (and if the technology works) smooth way of shopping.

So start browsing for recommendations on books or ask your friends and colleagues.
