The Ten Dumb Mistakes gives both young and experienced couples a new level of understanding of what makes a marriage work. It will coach you on the practical techniques you need to bring a new level of intimacy and love into your marriage- without expensive marriage therapy. Explains Rabbi Shafier ‘It is my fervent hope that through awareness of these common errors, more marriages can become the loving, satisfying relationships that Hashem intended them to be’.


The book has the full backing and haskomos from Roshei Yeshivos such as Rav Zeff Leff shlita, Rav Yechiel Yitzchok Perr shlita and Rav Shlomo Singer shlita:

“This book is a bracha! I can’t say enough praise about it. This is exactly what Klal Yisrael needs. I am a talmid of Rav Aharon Kotler and Rav Moshe Feinstein. I can tell you with certainty that they would have said:  Everyone should read this book. This book can save Klal Yisroel. Both Rav Aharon and Rav Moshe would have hugged you for writing this book.   May you go from Chayil to Chayil!”

 HaRav Shlomo Singer Rosh Yeshiva of Passaic Torah Institute
