If we protect our computer systems with spam filters and virus protection and firewalls and the like, why do we so quickly download such awful garbage into the most important memory storage system we will ever own?

We are what we think about over time. We are the accumulation of all our attitudes, beliefs, fears, hopes and dreams, all the thoughts that fill our minds on a regular basis. We are our own self-fulfilling prophesy. Our thoughts are the prisons we condemn ourselves to or they are the keys we use to unlock possibility and potential. There are ways to unleash that potential and live a life of deeply rewarding happiness.
