One summer his dad tore down a bick wall in the front of his business and told 12-year-old Will and his 9-year-old brother to rebuild it. A job they said was impossible. It took them a year and a half, but they did it. And he said,"now don' t you ever tell me there' s something that you can't do." You don't set out to build a wall. You don't say, "I'm going to build the biggest, baddest, greatest wall that's ever been built." You don't start there. You say,"I'm going to lay this brick as perfectly as a brick can be laid." You do that every single day. And soon you have a wall.
