A few things may happen by chance. But if you wait for the chance, good things will happen to you only when you are in your grave because things may take their time. Even quantum theory says that if you try, you can actually walk through a wall once in a “zillion” times because there is a pulsation of particles happening and you may walk through. It is just that before you reach that one zillionth time, you’ll have a cracked skull. When you live by chance, you also live in fear and anxiety. When you live by intent and capability, it does not matter what is happening or not happening, at least you are in control of what is happening to you. It is a more stable life.
