LEO (July 23-Aug. 22): Naturalist Charles Darwin formulated the theory of evolution, one of history’s most influential hypotheses. A crucial event in his early development as a scientist was a five-year boat trip he took around the world when he was in his 20s. The research he conducted along the way seeded many of his ideas. His writing established his reputation as a noteworthy author. Yet before he left, his father tried to talk him out of it, calling it a “wild scheme” and “a useless undertaking.” Did your parents or other authorities have a similar response to one of your brilliant projects? Now's a good time to heal the wound their opposition caused.
