Flow - Mihaly Csikszentmihalyi

Yep, his name is a mouthful. The book is simply beautiful, a study in logic, decomposition and analysis. By no means a light read, the book is dense, written by a Professor in the style of a textbook, at least for the first few chapters where Mihaly presents his hypothesis and the attendant entities which are interlaced in their exposition.

The subject is a simple one, but given its ephemeral nature, it is likely that the net required to arrest it be a strong one. A strong net is duly presented.

Read slowly, take notes if you can. You will find the effort worth the while.
