I've sways loved personality test. That's a guilty pleasure of mine... and this book provides good ones. They're are not all great and some are so obvious if you know yourself a bit that they're not necessary, but they are fun and I really think that some might help you know yourself better, maybe even more if you're younger. I'm old enough and work on my self enough during the last decade to know yourself quite well, but if you're ,younger, or just trying to work on yourself and try to know yourself better, this might help. So useful or guilty entertainment, you're choice! But a book well done!
