If I'm going to put "personality" on the page then I'm gonna talk about me. Yes, I am. Me, myself, and I.
I published my first short story when I was 39, and my first novel when I was 45. I would never have been able to write what I wrote without the life experiences that forty-five years had given me.
I'm thinking of character traits you never noticed before about those around you, or something in nature that sparked some sort of creative surge in your thinking or perhaps it's a smell, a sound, a touch... Think about the five senses.
