This is a brilliant book. The balance of advice is excellent, from medical to common sense to alternative therapies, this man has a really sound outlook on life. It's not just psychological advice either ~ the chapters about doing voluntary work, exercise and nutrition are very helpful too and are important factors often forgotten by people looking for more complicated answers.
It confirmed some ideas I'd read elsewhere and gave me new ideas also.
If you're wavering about whether to buy this book or not, don't hesitate, buy it! It's well worth the money and time to invest in your wellbeing and life.
