Relating to poetry – that it is for everyone. Even if you think you don't understand deeper meanings or things like that, most poetry is open to interpretation and as long as it made you feel something – it is for you.
Yes, as my poetry is mostly written from personal experience. And I'm going to be working on my Fantasy manuscript, in which I have dramatized a betrayal I went through (it's my book, I can do what I want to! I'm joking, mostly.)
All the time! I sometimes try and make myself write something – be it a short poem or finish something I've been working on. But mostly I just wait for it to pass, because staring at a blank paper or laptop screen makes me want to rip or smash said paper and laptop screen.
