The Mindful Day by Laurie Cameron. This book provides several practical tips on how to be mindful all day. It starts by helping you to get up in the morning in a mindful way, be mindful at work and then get ready for a mindful homecoming at the end of the day. The chapters are written in a brief and easily understood way. Every chapter concludes with a set of practical suggestions for mindfulness. Well worth the read. It can be read from beginning to end or by selecting specific chapters. I enjoyed reading the book and continue to refer back to chapters as a reference.
