Readers who pick up this book 20-30 years from now may find our current technology and my writings amusing. Medical technology is advancing at an incredible pace. In the past, varicose vein surgeries involved removing veins through incisions, but now veins are closed from the inside using thin, long tubes called catheters, either by sealing or heating, all through a simple needle insertion. And patients don’t even need to spend a single day in the hospital! Dear reader, applying everything I’ve written here might seem overwhelming. But remember, aiming for perfection and doing nothing is less productive than doing what you can—choose the strategies that resonate with you and seem logical. Don’t forget, improving by just 1% every day can lead to remarkable progress. Reading this book is an investment in yourself— happy reading
