Imagine you are an ice skater, playing a kockey game on the ice. With the stick in the hand, you are controlling the puck. You are skating elegantly across the slippery surface while always keeping the black disc close to you. You are convinced: nobody can take the puck away from you!
Now, you can either hold on to the puck or aim for the goal. If you hold on, you might become the best puck-keeper in the world, however you will never score a single goal. For the longer you keep the disc, the stronger your opponents want to snatch the puck from you. The more you hold on, the harder it becomes to even aim for a shot! Or you can go for the goal. At one point in time - sooner rather than later - you take a chance, haul out, and courageously take the shot. While you can never be sure whether it hits the goal, you can be sure that if you don't take the shot, you'll never score.
