It doesn't feel right don't do it, it's based completely on my own experience where I felt that It's not right or appropriate there I don't do that thing, and when I look back I see that , that was the best decision I ever took , but if do it and without thinking about it then it's worse decision I ever took, so it's based on my own experience and knowledge so far with my own life, it's completely based on my life experiences that I am sharing in this book, hopefully, it also helps you
