A rejected paper is always painful. But if you have a failed experiment experiment or a disproved theory there is always the silver lining that you have learned something you didn't expect. A good scientist should care more about finding out the truth than about having been right. A failed experiment or disproved theory is one step closer to the truth.
The key to taking this attitude is to bring out one's curiosity. See "Tim Harford: Facts Without Curiosity are Dead."
