I read this book through in 2 sittings but you can read one a day, to aid reflection and mindfulness. This collection is more intellectual and cultured than many quote books, esp for mindfulness quote books,. I counted at least 30 Ancient Greeks and there are Romans and Chinese philosophers too, Plenty of authors and artists, and many pop and film stars too. Deeply diverse, international, lots of women and notable people of all ethnicities. A keeper. I know I shall refer to this in future. And buy it as a present for those who perhaps need some reflection and focus in their lives. You will certainly feel wiser and calmer for reading the quotes in this book.
