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.
Time after I came to your gate with raised hands asking for more yet more. You gave and gave, now in slow measure, now in sudden excess. I took some, and some things I let drop; some lay heavy on my hands; some I made into playthings and broke them when tired; till the wrecks and hoard of gifts grew immense, hiding You, and the ceaseless expectations wore my heart out.
Take, O take, has now become my cry. Shatter all from the beggar's bowl. Put out this lamp of the importunate watcher; hold my hands, raise me from the still-gathering heap of your gifts into the bare infinity of your uncrowded presence.
