Whatever happens, happens.
To a degree, in our lives as each moment passes and different circumstances come to past, we have to realize that after they happen, there is no way to change them. We must take life for what it is, a series of unpredictable events ultimately out of our control. Sure there are ways to prepare for life, and understandably doing things such as setting goals and making a game plan for your life will take you to new heights, even to places you would of never imagined being. But life is too, very unpredictable.
