"Only the really plain people know about love - the very fascinating ones try so hard to create an impression that they soon exhaust their talents"

This quote by Katharine Hepburn speaks to the idea that those who are truly in touch with love are typically the most plain and unassuming people. They do not need to put on a show or produce an impression to be enjoyed, because they currently understand the power of love. On the other hand, those who are more remarkable and attempt to create an impression often tire their skills at the same time. They may be able to produce a strong impression, however they do not have the exact same depth of understanding of love that the plain people do. This quote recommends that the plain people have a greater capacity for love, since they don't need to place on a show to be loved.
