How do we live?

We live in a world that is filled with mystery. Mysterious people, mysterious journeys and endless adventures. A mystery for our futures and a mystery for others we know. We NEVER know whats next but... some people don't even care. How don't they care, how do they prepare? Anything can happen right? One day you wake up and do the ordinary and the next your WHOLE LIFE can just CHANGE. What do you do? You weren't prepared? But are we ever prepared? Was it your fault? Because you know you would have prepared knowing that something was going to happen, right? Our life sometimes just jumps right back at us. Giving us life changing choices that HAVE a decision to be made. We're never sure what we want and when we are.... Right when we start our journey we second question everything. Why do we do that? Why don't we just live? Why do we choose the harder way of life? Our lives are suppose to be fun and lived to the fullest, but every second we think about something or worry even if it's the pettiest things. So how do we live life? How do we enhance all that life has to offer if we just keep thinking, if we just keep wondering, and questioning and not preparing?
