Generally good advices given, an amusing narrating style is adoptted.
But sometimes some debatable private beliefs are introduced as facts with certainty that is just absurd.
For example in chapter 19 (smaller meaning of life) writer (rolf dobelli) claims: ;"creation of earth & life is meaningless & don't try to find bigger meaning in life otherwise you're wasting your time." !!!!!!!!!!!
Such direct nihilistic statement is just way too disturbing, specially when it is written or said in such imperative mood.
