Every morning when you wake up, you are given another day of life. This gift of life is precious. To say that it's precious is really a colossal understatement. Being alive is more valuable than anything else that one can own and possess. The greater your appreciation for being alive, the more enthusiastic you will be when wake up each morning.
Your Creator gives you life this moment for a reason. Your life is purposeful. Just imagine the enthusiasm you are going to experience when you realize that the Creator and Sustainer of the universe is saying to you, "I am giving you life this very moment. Appreciate it."
