Should I just finish my novel?

Don't care what people think, friend. Just write it and do what you love. You can't let people ruin your passion and make you feel like crap. You are talented and you love to write so do it. Never let the world get in your way. You are a writer and you can finish and publish your novel. Dealing with criticism is tough but we writers have to be strong. Say what you want from your heart and you can be the best. Work hard and have fun. Write because you love it.
