When Marconi suggested the possibility of wireless transmission of sound (the radio),he was committed to a mental institution. But people like Lincoln, Edison, and Marconi were strongly motivated.

God isn't calling us to a lonely, joyless existence with the promise of a delayed reward. God is calling us to live, to love and enjoy the challenge. God's formulas are roadmaps to freedom and peace. God is saying to us: "The only way to live is to be free. So save your heart for love and save your love for persons. Don't ever let any 'thing' own you. Don't let money or fame or power or the pursuit of pleasure put a ring in your nose and lead you around. Love persons and use things." And of course, this is the only way to live, to be free.
