Nice! I hope the thought-about-writing train keeps chugging. If this suggestion helps, whenever I need a push to start writing I grab my notebook and start jotting down some ideas that come into mind (personally, my go-to is characters conversing between each other; plot wise or not). Mainly, it's to get the feel of the idea before really getting into the nitty-gritty of organizing and planning.

Either way, good luck!
