Life is a mystery that remains unresolved till date which is good in a way because that is where all the beauty and excitement lies. If things would become predictable and programmed, all the vigor and spirit would be lost. However, human nature is such that it cannot get over its worries and doubts and keeps thinking as to what future has in store. This tendency may not be harmful always but one must try to avoid it. Living in present is the key to happiness and success. There is a famous Latin phrase that goes by the name of Carpe Diem and gives out a similar message.
