I think this one is a perfect way to explain to our kids why they need to remain positive, no matter how bad things seem to be to them.
Now I'm not saying that just because you think positive thoughts, that nothing will ever be negative in your life. That's just not realistic.
Besides, without a little negative and bad things happening from time to time we don't learn how to rise above it. We don't learn just what it means to have compassion to really have good, positive things in our lives because it is unknown (the negative things).
Lets set up our kids to live with the positive and to stop all the negative thoughts and feelings so that they can have more positive things in their lives.
The more positive we are, the more positive things and people gravitate towards us ... leading to more positive things and people.
