All to often in life we focus on the negative aspects or the bad things that are going on around us, instead of focusing on the positive and good. I know that I am as guilty as the next person for looking at the negative and for not being happy all the time, but all to often I am down and not truly enjoying life the way I should be. One never really knows how short one's life will be and each moment should be lived as if it were the last. You can't spend your life pleasing others or living for others, but you can live for yourself. You are the holder of your own destiny and if you are to be happy then it is up to you to make sure you follow the path that will bring this happiness to you. Otherwise you will be destined to be unhappy and to live an unfulfilled life. So in the words of Anais Nin:
Dreams pass into the reality of action. From the actions stems the dream again; and this interdependence produces the highest form of living.
So form your dreams and go after them, you only have one life so you might as well life it to the fullest.
