Whatever we do for the love of God benefits our souls and our lives in a way that ego-motivated actions never can. Whatever we do for the love of God is done with sincerity because it is not motivated by self-interest. We leave our concern for gain and loss, success and failure, in the hands of God. We stop considering ourselves as the sole cause of our actions and their results. Consequently, we become the instruments of a deep wisdom and love.
~ from THE KNOWING HEART by Kabir Edmund Helminski
If your still alive your mission on earth is not yet complete. People are happiest when they are so completely engrossed in an activity that they lose track of time and go into what is called a flow state. For this to occur, the activity must be reasonably challenging, neither too easy or too hard. It must be something that is of value to others, and it must be something that you love, that you can be passionate about. Your passion for your work will get you out of bed and into the workplace' even when you don't really feel like it, even when you are discouraged about your progress.
