Kaabil star Hrithik Roshan is thinking of writing a book on his life but he doesn't have a flair for writing. Hrithik in his both personal and professional life has seen many ups-downs and on writing book on his life, "I have thought of it, but I am not a writer. I am still thinking of it," he said. The actor stated, "Being a director requires internal calling. I don't have that calling. People might say that I am very involved, I have ideas but having an idea about something, tweaking something or adding something is different from creating from scratch. I don't think I have that." Meanwhile, on the work front, Hrithik hasn't signed any project till date.
