≪Kim Mi-Kyung's Forty Lessons is the first solo book from South Korean self-improvement mentor, creator of MKTV with 1.6 million subscribers, and head of the online knowledge community MKYU, three years after the reboot of Kim Mi-Kyung. It's been 12 years since Kim's first book, which earned her the titles of National Mentor, National Lecturer, and National Big Sister for her unique coaching and life solutions for women in their 30s. For those in their 40s who have spent the decade of their 30s dealing with the anxieties and fears of their 30s, but who still find life difficult and are anxious about the future, Kim has stepped in once again.

This book is a kind of growth manual for those who think it's too late to start something, for those who think they haven't accomplished anything by the time they turn 40, and for those who don't know how to spend their 40s. It's full of Kim's encouragement and solutions, including "life hacks" to help you get rid of your 40s anxiety, develop the mindset you need now, find balance in your multiple roles, and live a fun and meaningful second half of your life after 50. I recommend this book to all forty-somethings who have lived hard and who love their lives to the fullest.
