fierce determination............................

       One day when he was five, one of his cousins was having a birthday party, but Elon was punished for getting into a fight and told to stay home.  He was a very determined kid, and he decided to walk on his own to his cousin's house.  The problem was that it was on the other side of Pretoria, a walk of almost two hours.  Plus, he was too young to read the road signs. "I kind of knew what the route looking like because I had seen it from the car, and I was determined to get there, so I just started walking," he says.  He managed to arrive just as the party was ending.  When his mother saw him coming down the road, she freaked out.  Fearing he would be punished again, he climbed a maple tree and refused to come down.  Kimbal remembers standing beneath the tree and staring at his older brother in awe. "He has this fierce determination that blows your mind and was sometimes frightening, and still is."

-Walter Isaacson, Elon Musk
