I was still having voice cracks in grade 10. Don't worry about at all. Everyone is really different.
Everyone's different... What you should be doing is enjoying your youth and having fun rather than trying to be grown up because you have the rest of your life for that and being a kid doesn't last long enough! And... notice that when you become a senior your maturity plummets... to below zero haha.. don't worry about 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.
