Did you know that Leonardo Da Vinci was an 'illegitimate child' born out of wedlock to a notary named San Piero. In his book "Geography of Genius", Eric Weiner states that this was both a curse and a blessing: "Had he been born "legitimately," Leonardo would likely have followed in his father's footsteps and become a notary or lawyer. But those professions' guilds refused entry to illegitimate children... By age thirteen, most doors were already closed to him. Obstacles were placed, and he respondd to these. Again, the Power of Constraints in action."
