I love writing and I can see where you're coming from because people do put you down. I'm only in my teens and my family think that I won't be able to finish the children's book i'm writing. You just need to ignore them and concentrate on your own work.
It's your beliefs and confidence which will finish your book NOT theirs. Don't let them make you lose confidence. PROVE THEM WRONG!
You can do it!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
