The Let Them Theory, Mel Robbins Soft Cover Used in Excellent Condition - I just finished The Let Them Theory by Mel Robbins, and it honestly shifted the way I look at control and expectations. The idea of simply letting people be who they are - without overthinking, fixing or taking it personally - freeing! Please see our feedback. All of our items are accurately described and because most are vintage, we do not offer returns. All sales are final, we are experienced glass packers but in the off-chance something arrives damaged, of course we will make it right! As a re-seller, I am committed to providing accurate and detailed information about the condition of the products I offer. I will clearly state whether the item is new, used, refurbished, or open box. Any significant defects, damages, or wear and tear will be accurately described to the best of my knowledge. Please review the product description and accompanying photos before making a purchase and ask any questions before purchasing.
