Very sensible advice, really.
This is one of the self-help books that is going to permanently stay at my shelf (and I have read hundreds of them). Because I can really use the advice and the tips - and this is not always the case!
What I like about this book is the shift towards rationality vs the sometimes un-sensible world of emotions (no pun intended). Our emotions/instincts are not always based on reality (otherwise we would not make mistakes, some of them stupid). This books directs you towards realistic assessment of your possibilities in many life situations.
I have gained valuable insights. And some of them I am going to use quite immediately.

Some may be discouraged by the (quite many) profanities used here - but don´t let that discourage you. Pick what is worth for you.

But I also want to say - don´t leave your emotions and your good heart go away when doing the sensible desisions, as the sensible desisions might very well be the selfish decisions. Use your head well, but don´t let your heart get frozen.
