Has anyone else read this?

I read this book years ago when it was the first edition. It really spoke to me about some feelings I thought were really personal but turned out to be fairly common.

I read it again years later and it was a good read again. It has some really useful lessons and ideas I think.

I'm really curious if anyone else has read it, particularly someone younger than 40, and what they thought about it. If you haven't read it I would recommend giving it a go if you can find it, I'm going to give it another read now it's popped into my head.
