-        <p> Personally, I used to be more interested in movies and series than reading books. Reading books always felt like a chore to me, and I struggled to find books that kept me engaged and interested. However, over time, I discovered the world of self-help books and found myself drawn to the practical advice and guidance they offered. These books helped me learn new skills, gain new perspectives, and develop a better understanding of myself and the world around me. My favorite books include: Ikigai: The Japanese Secret to a Long and Happy Life and The Subtle Art of Not Giving a F*ck. </p>
