Forty-five figures, each more famous than the other, wrote letters to their thirties... We all think about the past from time to time and question our own lives; we reflect on what we have done or failed to do, our successes, or our failures. The things “I wish I could” and “I’m glad I did” mingle. In Letters to Thirties, forty-five figures, each more famous than the other, wrote letters to their thirties... They not only reflected on their lives but also shared their experiences and gave advice to today's youth alongside their own youth. Just as Meri İstiroti, the author of Letters to Thirties, which serves as a guide for all young people throughout their journeys in life, says: "In this book, there are precious experiences gained, achievements accomplished, and mistakes made to reach the top... Even if they do not happen to us, we can move along our paths in life more consciously by reading these experiences."
