Hmm I am a bit confused by your answer. I read your profile and realize you like philosophy. I hope this isn`t a case of too much philosophy. With all do respect, this is a very general thread or topic, and you asked a simple and non-philosophical question, " how can one use this book in their day to day life?"
I gave one answer and it is as simple as that. I don`t swear by this book nor any other one single book. So, again forgive me for saying it sounds like you like to hear yourself talk as your answers completely didn`t address what I wrote as a response from your initial question.
I agree with you this book is not a holy grail, but a guide for those whom it makes since too, or whom it works for. I just merely pointed out how I can use part of it, just like I can use parts of hundreds of other books.
You asked a simple question, you got an answer, and then went off on a philosophical rant. So I am not sure I got your point as relating to your initial inquiry, you seem to have digressed.
However, let me finally say this. I think what you were initially trying to say, is that most people read a book like this get inspired for about 5 minutes and don’t apply it truly in their life. So the question then becomes, what was the point, other than a temporary sense of enlightenment. Bruce Lee the martial artists use to quote all the time, “You can’t merely learn, but you have to apply. Only then can we change what we learned to work for us and make it our own. Keeping what we make our own and discarding what we find useless.”
