I love this type of thinking but it doesn't have to lead to the conclusion that nothing matters. How about celebrating the fact that we have been given this brief opportunity of life, gifted with a consciousness that allows us to contemplate our place in this universe in this manner and to communicate this with others, that's a true miracle. We are able to experience so much if we don't allow ourselves to be constrained by mindless activities and others ideologies of how we should or shouldn't live. I choose to fill my days with what makes me feel happy and gives my life meaning and purpose. This helps me not be overwhelmed by the mind twisting enormity of this universe which we are only just beginning to understand.
