I came across this book because so many PensionCraft clients had read it. Tony Robbins is not a financial expert, as he is at pains to explain. However as a world-famous motivational speaker he has access to some of the best minds in finance. He drew on those minds to produce this book which explains how to avoid the fear of investing and maximise your chances of succeeding when you invest.
He explains why you should avoid excessive fees, use asset allocation to diversify and look to get the best possible return for the least risk, and that you should use tax efficient savings whenever possible. He also motivates you to overcome your fear of investing with some historical facts about market long-term returns. All sensible suggestions. The drawback for UK investors is that it is slightly US-centric but it has universal principles that are useful for anyone, anywhere.
