Harriet Tubman conducted 13 rescue missions on the Underground Railroad over a 10-year period. Those long journeys to freedom resulted in lots of hungry people. Tubman was a professional cook - which provided her mission's startup capital, and creativity under pressure. She once stopped at a market to buy 2 chickens, and almost came face-to-face with a former overseer ... so she dropped one of the chickens and started to chase it. The comedy allowed her to escape unnoticed - even though everyone could see her. When they can't see you, learn to take advantage of being "hidden" and underestimated.
