　　Nothing ventured. Nothing gained. If our great explorers and scientists did not live by this creed, where would we be? I think that we must all take risks in our lives, but these must be calculated risks. Like the great thinkers of our time, we must plan carefully, seize all opportunities, and reevaluate our plans.
　　There is no such thing as a chance occurrence. Columbus in his search for the Indies drew maps, plotted his route carefully, and set out. Madam Curie worked diligently in her laboratory recording every aspect of her experiments. You need to have a careful plan so you can measure your success.
　　Even with a careful plan, changes occur. Columbus was looking for the Indies, but ended up in the Caribbean. Lewis and Clark were looking for a river passage west, but discovered much more. You have to be ready to take advantage of new things as they occur.
　　When things go against plan, you must be ready to change direction. Columbus didn’t bring back spices from the East Indies, he brought back gold from the West Indies. It is important to see the positive side of things. Make your mistakes work for you.
　　You will never succeed in life if you don’t take chance. But before you start, you must plan carefully so you are ready to take advantage of every opportunity and turn mistakes to your advantage.
