Interesting question. First and foremost our single most important goal should be survival of our planet. Unless we all stop being so selfish and start caring about all the little ways in which we adversely affect our "home", we won't have a "home" for much longer. We need to address climate change and the chain of causality that accompanies it. We need to address world population growth. We need to address the issue of food security. We need to address the rapid extinction of animal and plant species. We need to address corruption in governments around the world. If, however, we were to put all that aside and for a moment assume that the RTOTD is simply about a selfish goal unrelated to the life of our planet and those around us, then I'd have to say that our individual goal should be to pursue our passions in life, strive to be happy and fulfilled, and pass on our joy to others.
