Though we never really know when lightning will strike and the unexpected happens, we can do our best to prepare for the worst so it's less jarring. In life, we must be prepared, but also flexible. Things can change in life at the drop of a hat, and we must be ready to adapt.
How many "wow" moments have you had in life where something unexpected occurs. When faced with trials and tribulations, we must first use our available skills and resources to face these head on and pull through. After it's all said and done, look back and see if there is anything you can do differently if faced with similar circumstances in the future. Learn from the mistakes you made and do what you need to prepare for the future.
