Misserable or Happy your choice

I was told dreams never last. That you only make it when you've accomplished something to everyone else. That it's better to quiet while your ahead. That hope is for fairy tales and childern. The question that comes to my mind after all this is then why is life worth living at this point? If dreams, hopes, accomplishments, and believing in the impossible means your a failure. Then I would rather be a failure and be happy than a perfect robot and be misserable. Its all about the choices you make and choose to fallow.
