I was once optimistic about long distance space travel. However, the hazards to our frail human body's in space, 0 gravity, the distance to other stars, and this, in my opinion, is the most daunting; cosmic rays, has made me a bit jaded on the subject. I truely hope I'm wrong and human ingenuity can overcome these obstacles.
