It's been said that you are what you read.
The person you are, and what you will become, depends largely on what you fill your mind with.
If you spend 4-5 hours a day watching 24/7 cable news, then you will probably feel stressed out because there is always some BREAKING NEWS every five minutes.
If you spend that time watching mind-numbing reality shows, your view of reality is skewed. I used to work with someone who was on one of these wife-type shows, and it depicted the children she had as being rambunctious and unruly. This was the complete opposite of what their family was really like, but it supposedly made for better TV.
If you spend a few hours each day reading or listening to some of the podcasts (certainly there's more I haven't discovered yet) that I've mentioned, then you'll find yourself being steered in a more positive direction.

What are some of the books that motivate you?
