Word that describes me

a world i come from makes me want to go to mars because there are so many researches and articles saying that the world is going to die, and that human kind is doomed to eventually fail, but i do not want to give in to that possible reality because there is always ways that human kind can survive. there are so many people saying that it is possible to go to mars so why give up when we have a hope of surviving even if it son a different planet.  

shift key is broken on keyboard os i could not capitalize.
