In this updated edition of the bestseller published ten years ago, Oprah shares what she has come to know for sure in the last decade.

After film critic Gene Siskel asked her, "What do you know for sure?" Oprah Winfrey began writing the "What I Know For Sure" column in O, The Oprah Magazine. Saying that the question offered her a way to take "stock of her life," Oprah has penned one column a month over the last twenty-four years, years in which she retired The Oprah Winfrey Show (the highest-rated program of its kind in history), launched her own television network, became America's only black billionaire, was awarded an honorary degree from Harvard University and the Presidential Medal of Freedom, watched friends and colleagues come and go, and celebrated milestone birthdays. Throughout it all, she's continued to offer her profound and inspiring words of wisdom in her "What I Know For Sure" column in O, The Oprah Magazine.

Now, for the first time, these thoughtful gems have been revised, updated, and collected in What I Know For Sure, a beautiful book packed with insight and revelation from Oprah Winfrey. Organized by theme — joy, resilience, connection, gratitude, possibility, awe, clarity, and power — these essays offer a rare and powerful glimpse into the mind of one of the world's most extraordinary women. Candid, moving, exhilarating, uplifting, and dynamic, the words Oprah shares in What I Know For Sure shimmer with the sort of wisdom and truth that readers will turn to again and again.

Must have
These things a freaking AWESOME! If you're doing a big sound deadner job, you need thees! The 3 different sizes are perfect for the different shapes in the floor pans. Well built, good quality and they have a nice weight to them. Just buy them and thank me later. For $15.00 you can't go wrong.

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.
