The Decision Book: Fifty Models for Strategic Thinking

Very approachable book which made models much less intimidating for me. It was an easy and quick read with great illustrations. There's a great mix of models for business, conflict resolution, self-improvement, etc. So you're most definitely going to find something you can apply.

It is my first book about models and maybe it wouldn't be as useful for model thinking veterans, but it seems like a really good introductory book for models to me.
