Try to focus on your website first. Medium demands commitment. If time is a constraint and you are not able to serve your Medium users, it is advisable to repurpose your content for Medium rather than creating original content.   Also, Medium allows you to repurpose or republish your content for better reach. In case your published post does not receive a great number of views, you can choose to delete and republish it after polishing the content. It’s possible that a blog that didn’t work well last time may turn out well the next time.
