Hello, this is Osman. This is my first letter of this newsletter. I hope I can provide something valuable to you. Nearly 2 months ago I wrote a blog post on Medium about my self-improvement journey. As I mentioned there, I started a Self-Improvement Challenge which contains reading books about sales, negotiation, human nature, and money. I will write weekly emails about the journey and share the summaries of the completed books. Stay tune! Best Regards. Osman. Any question: osmannurierdogann@gmail.com
