My fatal flaw

At school our intern, Ryan, is reading us a book called “The Thief of Always”. In the “Thief of always” all the main characters have fatal flaws in the book. One example is peer pressure. So, our intern asked us to right this post about what we think are flaws are. I think that one of my fatal flaws are procrastination. I always want to do something later. Usually I practice piano and I never put my pieces back on the shelf. So, later my mom yells at me and lectures me to always put my pieces back and then the next day I leave it on the piano again and then I get grounded. I think that being more responsible and being organized will help me.
