re: snooker- miles again avoids the issue.
debono Martin Luther King did a lot more than dream, he was a down to earth activist who worked hard to move things in the direction he wanted. In that way he made some of his dreams a reality.
His ultimate dream remains as elusive and out of reach as the idea you have, and I think there is a 99.9% probability that is where such dreams and ideas will remain.
Therefore we can only try to do the best we can with the world we have now.
