YES YES YES ...
Format: Hardcover
The message and encouragement in these pages are for a thoughtful read and read-again. It has helped me understand and pursue an unhurried being, care for my soul enriching my relationwith with God, others and myself. Hint: It's not about time management or eliminating calendar commitments; can be but it's more than that, it is care of one's soul before God. This book has focused me .... as I said, it's a read and listen once twice thrice kind of book. Much to savor.
