Nothing! There is an automatic assumption that negative is realistic and positive is unrealistic. That is pure madness. It is reported that more than 90% of what we worry about never happens. That means that our negative worries have less than a 10% chance of being correct. If this is so, isn't being positive more realistic than being negative?
If you think about it, the important issue is not which is more realistic, but rather, "Why be miserable when you can be happy?" If being a Pollyanna creates a happier world for you and those around you, why hesitate for one more moment?
Nothing is realistic or unrealistic-there is only what we think about any given situation. We create our own reality. What does all this tell you? STOP FEEDING YOURSELF NEGATIVE THOUGHTS. Negative thoughts take away your power.... and thus make you more paralyzed from your fear.
So, why don't people think more positively? People don't understand what being a positive thinker requires. It takes a special commitment and requires a great deal of practice. And then once you get it all down perfectly, a maintenance program is a must. If you don't practice, you lose the skill. This is the point most people don't seem to understand. So how do you stay positive? Stay tuned.
