A book to read which has been much to learn ...

A book small in size but big in its content. The authors mastered their subject, which is explained clearly and with humor. Anything goes: methods, organization, motivation, stress management and even food, sleep and health.

However, a caveat about their concept of "Conceptogram" (a kind of chart used to take notes which summarize what is known about a subject) that I find a bit complicated. I prefer the concept of "mind maps" developed in "A good head" by Tony Buzan (the two works are in fact complementary.)
