The adult is when you eat lunch before you go grocery shopping. I don't need cookies. I don't need candy. When you're done, you have more money in your pocket and you don't feel guilty for your choices. You allowed yourself to reflect about it more.

If you read a newspaper today or watch the news, you know that the child personality dominates our world. That's why we have wars and other conflict. Leaders need to move to the adult and then teach others how to do the same. Leaders know the success stories and accept the challenges. Now they're providing the direction for others to follow.
