A Morale Boost from Sherlock Holmes

In the opinion of Sherlock Holmes, modesty is not a virtue. To a mind as precise and logical as his, downplaying one's abilities is the equivalent of a lie. Likewise, if taken to an extreme, this sort of modesty could lead to chronic underestimation of oneself, lowering a person's self worth—a vicious cycle. Better to be accurate and generous with yourself from the start.
