Before there can be visible change, there must be invisible change. This invisible change happens inside you. It happens in your thoughts, spirit, emotions and body.
Greatness does not require a Herculean effort but it does require an Olympian approach. Persistence, then patience using strong faith is the approach of Olympic athletes. They work on something for many years and then in four year intervals before their ultimate goals can be realized. Olympic athletes prepare for greatness throughout each day. They do so without applause.
