Napoleon Hill Thought of the day. Experts in human behavior have discovered that it is virtually impossible for an individual member of a group not to be affected by other members. Likewise, the group itself is only as strong as its weakest link. It is rarely possible for the entire group to raise itself to higher levels of achievement than that of which the weakest member is capable. It is only possible for individuals who break out of the group to exceed the potential of the group as a whole. Don’t associate with those who are afflicted with the mental sickness of constant negative thinking. Associate with happy, positive, productive people. Your time is an asset to be managed more carefully than your money; spend it with people who share your desire to succeed and your commitment to maintain a Positive Mental Attitude.
