For me, it’s peer pressure in a positive sense 🙂
I write my best funny stories when I know someone asked me to do so and is waiting for me to deliver. I am thinking of my best friend from middle school who continuously asked me to write new stories about our favorite characters. It’s been about 10 years since then, but that time was euphoric and so gratifying for me creatively.
Having at least 1 person to work for gives me a purpose.
