How to Enjoy your life and your job

Of course I saw this book everywhere, but I never read it because the title put me off. I imagined some list of sly tricks to con people. I was wrong, the book is very compassionate and never crosses the line of good ethics. The simple concepts are well explained, and while I will not “work on the program” I'll try to apply at least some of the ideas.
The book shows a little bit its age, most modern self help books will try to use a little bigger dataset and scientific papers to justify the thesis, while Carnegie paradigm is a lot more based on anecdotal evidence, but it almost never sounds false or far fetched (while for example the 7 habits of highly effective people is a very gratuitous book, in my opinion).
Good and positive read, it doesn't invite you to change anything in your deep convictions and values, it just invites you to be a little more positive in practical, relatable ways.
