Not sure what is the title in English....But I guess something in the line of 'A workweek of 4 hours'..From Timothy Ferriss... I never read a book like that thought it would be garbage... Well it is garbage but it lets you think and gives you energy;..
And I am also reading Michael Crichton's Congo.. I always liked his books (like Jurrassic park and the Lost World) sadly they can feel a bit outdated...
