If something is dropped in the water or in the river, you cannot see the things dropped within the water by agitating the water. Just stand still for some time. As soon as the water is settled up, you will see the things as they are. So as soon as our enthusiasm is agitated, it is better to sit down in any temple suitable and chant Hare Krishna. There is no question of being disappointed. After all, we commit so many mistakes. That is human nature. To err is human. That is not the fault. But try to rectify with cool head.
