Graphic novels are not traditional literature, but that does not mean they are second-rate. Images are a way of writing. When you have the talent to be able to write and to draw, it seems a shame to choose one. I think it's better to do both.
You have 2 choices in life. Cave into pressure, stay stuck and allow life to continually overwhelm you. Or step out into the big unknown world, face your fears and aim for a life with purpose.
