I am a B.Com graduate working as an accountant for the past 15 years. I am 35 years old. Now, I want to become a film critic/copy editor. Can I change my profession at this age? I have written regular letters to the editors of various newspapers for the past four years, and a number of them have been published. This is the only experience regarding a film critic\copy editor. Will this help? Is there any specific course for becoming a film critic\copy editor? Please inform.
