If you're not doing something with your life, then it doesn’t matter how long you live. If you're doing something with your life, then it doesn't matter how short your life may be. A life is not measured by years lived, but by its usefulness. If you are giving, loving, serving, helping, encouraging, and adding value to others, then you're living a life that counts!
