Natural Highs by Holford and Cass

I was interested in this book because I felt a healthy pick me up might be nice, and curiosity got the better of me. I don't know what I'd expected, but the recommendations are to take an awful lot of expensive supplements.

Kava, NADH and S-ame are allegedly herbal mood enhancers, which might be worth a try, a powerful multi-vitamin and mineral should ensure you're not blue because of nutritional deficiencies. Omega 3 is a recommendation that I include in my daily diet anyway.

Nothing is Impossible by Christopher Reeve

This book was written by Christopher Reeve, the actor who played Superman in the 1970s and '80s movies. He was paralysed in a horse riding accident in 1995, and died in 2004 of a heart attack, following a bad reaction to an antibiotic.

In the book, he tells how he started to gain some movement back in his limbs - five years after the accident, which was unheard of among the medical profession and was thought to be impossible. It led to new therapies being developed to help people with paralysis regain some movement.

Emotional Intelligence by Daniel Goleman

This book starts off looking at neurology - the workings of the brain - and recognising that some unconscious emotional responses are triggered before we're even aware of them, or have a chance to think what an appropriate response would be. Our initial reaction therefore, is instinctive, and we may later regret having responded in the way we did. Harnessing the power of emotional intelligence can get us responding more appropriately. A lot of emotional intelligence is developed in childhood, given the right circumstances to develop a healthy social and emotional life. There are ways to teach people emotional intelligence, and examples are given throughout the book.

365 Ways to Feel Better by Eve Menezes Cunningham

This book is rather more spiritually focused that I'd expected, so if you're a fan of angels, crystals, meditation, yoga, and other 'new age' approaches to feeling better, you might enjoy it. Personally I'm finding many of the ideas don't appeal and I'd rather go for a walk, which I know will boost my mood! However, there are lots of ideas, so if the day-to-day readings aren't doing it for you, you could dip in to any part of the book, looking for something that does appeal. It doesn't really matter what order you do things in.
