What keeps me going in life are my dreams.
I cannot attain them just yet, they're always tantalizingly out of my grasp. It's like in those cartoons where the horse or whatever has a carrot hanging in front of it that makes it walk. The horse may hate being taunted like that, because it is trying to get the carrot. It cannot possibly understand completely where they are going and why, it is just best if they focus on their rider and keep walking forward. In the end, the horse does get the carrot. And boy, is it satisfying.
