Yes I would.
People reading your blog, or listening to your podcast or watching your video’ is just a by-product of you contributing. You are releasing your art.
There are so many times when I see the lessons of Stephen Pressfield’s The War of Art. The purpose of you doing your work is not to be rich or to be famous to get notoriety. The purpose is to tap into the muse, to find the creation that already lives inside of you, and allow it to come into the physical world.
If you do that long enough, people will read your work.
It’s almost impossible to get people to fall in love with your work unless you allow them to find it. They find it and they say “I feel that way too.”
So yes, write every day even if no one else sees it.
