"Don't worry if you have problems!" It is easy to say until you are in the midst of a really big one.The only people who don't have troubles are gathered in little neighborhoods.Most communities have at least one.We call them cemeteries.If you're breathing, you have difficulties.It's the way of life.And believe it or not, most of your problems may actually be good for you! Let me explain. Maybe you have heard the Great Barrier Reef, stretching some 1,800 miles from New Guinea to Australia.Tour guides regularly take visitors to view the reef. On one tour, a traveler asked the guide an interesting question."I notice that the lagoon  side of the reef looks pale and lifeless, while the ocean side is vibrant and colorful," the traveler observed.Why is this? The guide gave an interesting answer, "The coral around the lagoon side is in still water, with no challenge for its survival.It dies early.The coral on the ocean side is constantly being tested by wind, waves and storms.It has to fight for its survival every day.As it is challenged and tested, it changes and adapts.It grows healthy.It grows strong.And it reproduces." Then he added, "That's the way it is with every living organism." That's how it is with people.Challenged and tested, we come alive! Like coral pounded by the sea, we grow.Physical demands can cause us to grow stronger.Mental and emotional stress can produce tough-mindedness and resiliency.Spiritual testing can produce strength of character and faithfulness.So, you have problems? No problem! Just tell yourself, "There I grow again!" Remember: A smooth sea never made a skilled mariner. In the writer's opinion,   _  .
