The Art of Loving

One of Erich Fromm's most famous works - "The Art of Loving" - is dedicated to the complex psychological aspects of the emergence and maintenance of such a seemingly simple feeling as love. 
Is love really an art? If so, it requires effort and knowledge. Or is it just a pleasant feeling? 
For most, the problem of love is primarily the problem of how to be loved, rather than how to love oneself.
