The consequences of this problem make themselves felt in bookshops. When you go to a large bookshop and look at the self-help sections, as I sometimes do -- if you analyze self-help book sproduced in the world today, there are basically two kinds.

The other kind tells you how to cope with what we politely call "low self-esteem," or impolitely call, "feeling very bad about yourself."
