Everything, everyone, has a purpose. Take this seed for example, it is made to grow on this tree and let go at the appropiate time and take flight, land some where new, and grow again.....to perpetuate the life cycle.
People can be like this seed. They can grow and hang on to the tree and not let go. When this seed didn't let go it got covered in snow and ice. It formed this beautiful icicle, but did it meet it's full potential? Maybe being a seed covered with snow and ice is exactly what it was made for.....but what if it didn't let go and be a tree?
