All of us at some time in our life will go through dark places. We may have experienced the loss of a love one, a critical illness, divorce or a child who broke your heart by dissapointing you with their action or behavior. It's easy to get discouraged and give up on your dreams. You know, just settle for whatever.
Think of it like a seed, if the seed stays in the light it will never become what it needs to be. The seed needs to be planted in the soil, in a dark place so that's what inside will come to light. In ways, people are similar. Things such as dreams and goals, various talents and potential that will only come to life in a dark place.
In the dark place is where we really grow. Character is developed, we learn to trust and persevere. In the dark places we learn to listen, reevaluate our priorities and spend time with family. You have a better appreciation for living.
We enjoy the the good times a lot better and everything appear or seem to go our way. For me, "it wasn't the good times that have brought out the best in me. It was the times I didn't think I could make it because I couldn't see a way. It was the dark times that helped me find courage and strength."
