In this book, the great guru of the Spanish economy, Leopoldo Abadía, author of La crisis ninja y otros misterios de la economía actual (which sold more than 150,000 copies), father of twelve children and grandfather to forty grandchildren, addresses problems that affect all families at one time or another. The children’s education, managing the domestic budget, family relationships..., these are just some of the themes which Abadía explores in his unique instructive style with simple wisdom and a sense of humour.
