That is the most beautiful way to spend life. I like to believe that the meaning of life is to give to others. I read the book the Alchemist by Paulo Coelho, and he said, “when you really want something it is because that desire originated in the soul of the universe. It is your mission on earth.” The afore mentioned quote makes me think about what you said about “knowing” what you wanted to be when you were seven. Perhaps, you have found your mission on earth. I wish you the best of luck.
