Of course, it's difficult to get stuff to post regularly. But you need to understand how you cleverly publish your post. As you know, there is some best time to post on different social media platform to get more engagement. You should have these days and time in your mind while scheduling your post. You don't always need to post your own stuff, you can share somewhere else post, or some news, post which are in trends currently. Always sharing your own stuff make your followers unfollow you. I hope you get your answer how to post regularly.
