I often hear people say to others, "think outside the box" in their efforts to have them be more creative. In my mind, if you have to think outside the box, then something is wrong with the box.
If you were having problems in your marriage, would you look outside your marriage for happiness? That would be considered an affair and you would not be acknowledged for your creativity. You would probably want to work on your marriage and if you tried everything possible and it didn't work out, then you would want to make a change.
What if your box was so inviting, inspiring and motivating with endless possibilities? How could you tweak, change or modify your thinking so that the world of infinite possibilities becomes your box?
