In The Law of Success, a very, very good book by Napoleon Hill - perhaps one of my favorites all time, in fact - Hill discusses, as one of the 16 tenets of success, the necessity of having a pleasing personality. Part of his recommendation is for listeners to be agreeable.
If you look at most people in Western society, I don't think this aspect of a pleasing personality - being agreeable - is much of a problem for them. In fact, I think one of the overriding problems for Westerners is in being too agreeable - so much so that anyone willing to be a bit less agreeable is able to easily steamroll them into uncomfortable submission.
But, that's a topic for another time. What I want to discuss in this article is why it's a good thing to be a little hard to please... at least some of the time.
Because if you've long made a habit of being overly agreeable - and there really can be too much of a good thing - a little dose of pickiness may just be in order.
