Sometimes, we are spiritually frozen. This book will thaw you out and heat you up.

Nissim Black - Rapper

I love this book and how Rabbi Wildes has created an engaging, easy-to-read, and downright inspiring daily challenge. The anecdotes he cites are relevant, timely, and touching. . . . I wholeheartedly recommend it.

Moshe Kinderlehrer - Publisher of the Jewish Link of NJ / Expanded Edition

Hashem gives us physical muscles and spiritual muscles. Just like I have a training camp to make sure my muscles are ready for when I have to get into the ring, the book is a sort of guide for a spiritual training camp so that you will have the preparation you need before you pray in the synagogue.

Yuri Foreman - Israeli Professional Boxer, WBA Super Welterweight Champion, and Ordained Rabbi

Rabbi Wildes guides us to become the best version of ourselves. The 40 Day Challenge is recommended reading – not just during Elul and the Days of Awe, but for the rest of the year as well.

Julian Horowitz - Founding Member and Music Director of The Maccabeats

The potential of these holy days comes alive as Rabbi Wildes challenges us to concretize our commitments and set pointed practical conversations for lasting change.

OU-JLIC Director, and Jewish Press Book Reviewer - Rabbi Reuven Boshnack

In The 40 Day Challenge, Rabbi Mark Wildes offers a series of gems on Jewish thought - short essays that are accessible, honest, and authentic.

Pithy & powerful, Rabbi Wildes takes us on a 40 day journey to becoming a better version of ourselves.

Charlie Harary - Motivational Speaker and Author of Unlocking Greatness

What a brilliant resource for scholars and laymen alike to make the forty days between Elul and Yom Kippur not only meaningful, but poignant and transformative. You will not only savor the wisdom of our sages, but will relish how Wildes peppers in various pertinent historical allusions along the way! A must have for Elul and in preparation for the Yamim Hanoraim.

Nava R. Silton - Fox 5 Psychological Correspondent

Rabbi Wildes offers an inspiring and practical field guide that will help readers take full advantage of a period on the Jewish calendar earmarked for unparalleled growth and Divine mercy.

Yehoshua November - Author of L.A. Times Book Finalist God’s Optimism

My dear friend, Rabbi Wildes, has yet again gifted us with a great resource for personal growth. Reading the essays of The 40 Day Challenge will inspire, inform, educate and entertain you, as Rabbi Wildes seamlessly weaves together Torah sources with stories, research and real life practical advice.

 ABOUT "THE 40 Day Challenge"

While many of us physically attend High Holiday services each year, how many of us feel spiritually prepared and inspired? The forty-day span preceding Yom Kippur is the holiest time on the Jewish calendar, precisely because it was designed to help us find meaning, inspiration, and purpose.

What kind of person do we want to be and how can we feel more connected in the coming year?

Written in an approachable, uplifting, and accessible style, The 40 Day Challenge is an invitation for people who believe there is more to life than the daily grind. It offers the reader easily digestible and compact Jewish wisdom, each day for the 40 days from Rosh Chodesh Elul leading up to Yom Kippur. Each daily reading is followed by a challenge question so it can serve as a spiritual diary as you approach the High Holidays. This year, instead of just “showing up,” prepare yourself with a Torah insight written by MJE Founder Rabbi Mark Wildes, who has spent his life inspiring Jews from all walks of life. “The 40 Day Challenge” will help you use this special time, and really every day of the year, to better connect to the people around you, make a positive and impactful change in the world, become the very best version of yourself, and connect to God at a time when He is closest.
