It's pretty much just a huuuge book of different tips that helped him become more content/deal with life easier, that he hopes might also be useful to others in some way. There's a lot of funny moments in there too, and I guess even people who don't know who Derren is would probably find some of it of us. I've always loved him ever since I first saw him on TV, haha. There's quite a bit about stoicism in there, which I knew nothing about before listening to the book! Funnily enough, I've since finished 'Happy' and have moved onto his more recent book, 'A Book of Secrets' haha. Which has more personal stuff from him in there like what happened with him and his family during Covid lockdown, but also again some helpful bits of info and advice about life and stuff!
