It feels good when we accomplish our goals. There are a certain number of things that make it rewarding to us. It is one motivator for adventurers to get out and adventure. They know what its like to reach the end, the finish line, the top. They enjoy subjecting themselves to physical and mental strain because they understand that the more they push themselves the better their reward will be when they finish. Pushing themselves separates them from the rest, and allows them to accomplish things that will earn them respect from others. It can give them a sense of identity. Along with that, adventurers take with them the satisfaction of successfully completing their goal.
