Everything in Its Place

I don't usually go in for productivity books, but this book is more about organizing yourself - which, yes, increases productivity - but it also is about staying focused and clear about the things that are important to you. I have a terrible habit of taking on too many things and staying too busy, and then wondering why I don't accomplish the things that are important to me. Having worked in restaurants for several years, many of these tactics resonated with me. I got a lot of inspiration from this book and began implementing it right away. Staying a day ahead in your planning makes a huge difference (and truly helps with anxiety).
