We only grow in the crucible of adversity. Every hardship, even every disappointment, should be the seed of a new opportunity. Let me give you an analogy: Think of a little stream of water. It has no strength in itself. It is shallow and weak. But if we put a dam across it, this obstacle will cause the water to back up and get depth. This obstacle has caused the water to have strength and power. It can now generate power to drive a locomotive and it can turn the wheels of industry.
