I don't know why I read these types of books, because they usually just leave me feeling annoyed rather than enlightened.

This book is full of simple, common sense suggestions. It includes groundbreaking advice such as get more sleep, eat more fruit, exercise, don't surround yourself with bad smells and be open to new ideas. Who would have thought incredibly obvious things would make me feel happier?

Actually, I want to rant about something small that was mentioned in this because this always rubs me the wrong way: stop telling people to never watch television ever because it will crush your soul and make you a uncreative robot, incapable of enjoying life. Yeah, you shouldn't watch it 24/7 but how about we all remain quiet and realize that television is a form of creativity? You know, there are writers, costume designers, actors, directors involved in about 99.9% of the shows you watch and I'm sure they'd be stoked to hear that their dreams and talents are actually the work of Satan. How about we support all kinds of creativity instead?

Also, screw this book - set big goals for yourself if you want to! Don't hold yourself back because you're worried your goals might be unrealistic. All you're doing is limiting yourself because you're worried failing will make you feel bad, but I'm pretty sure nobody would accomplish anything big if we're all too scared to set a big goal.

A terribly boring read.
Although the first few 'secrets' were quite agreeable, as I delved deeper into the book, I found myslef not just disagreeing with several of the 'secrets', but taking a long time to decipher what Niven has written.
This is the first time I have pondered about the editor and questioned the publisher while reading a book.
The writing is simply atrocious. Many of the sentences are made difficult to comprehend with unnecessary use of double negatives to illustrate points and also many of the examples and wrapping final paragraphs seemed to be linked extremely vaguely.
I wanted to stop reading half-way but persevered and ironically, I came across a 'secret', which is to stop doing something that is unprofitable at once, without worrying about not completing the task.

Nie daję oceny, bo w sumie nie jestem w stanie jej dać. Książkę ostatecznie porzuciłąm, gdyż jednak chyba powinnam ją zostawić na faktyczną drugą połowę mojego życia, do której póki co dość daleko więc i rady zapewne stracą na wartości.

The suggestions are very beneficial even though they are very common known things. I have a disappointment for the research section: The statistics doesn't say me anything but just numbers since the references are not stated as a footnote... Particularly, I loved the 23rd topic which is about tomato. As a being tomato hater, I just become very excited when it is claimed that the cooked tomato might be 2.5 times beneficial to the raw one comparing their lycopene amounts! Overall, the book is O.K but I cannot assert it's worth to read it...
