Guardian Angels?

Do you believe in guardian angels?
It's often said every person has one guardian angel. If this is true, I think they are so generous and patient. Then, I think I'd better don't give up my goal, because if there is an angel looking over me, she (or he?) is like an audience. Any audience doesn't like watching a game which the player doesn't show his sincerity. So I'd better don't give up.
