Capture every thought.
Put these thoughts in an easily accessible database, like in Evernote.
Every day at a set time, come back to this database of thoughts, notes, and observations and work to improve an idea or two by writing more about it. See which idea is formed in your head.
Come back to it the next day to give a title and shape it depending on whether you want to publish it as a blog post, Twitter thread, a long-form essay, a video, or an audio version.
Because you are creating a database of notes, that will work as a base of creation, you’ll never be short on ideas, and because you do it every day, you’ll be consistent in creating content and will become a consistent creator.
