I do not find it difficult at all. Since I pick topics that are part of my everyday life, I just write or video blog about what I am doing.How difficult do you find content gathering for website and SEO purposes?
One of my current projects is a patio garden in containers. So I did a couple of videos about the project, and posted a couple of blogs about it.
The real "key" to blogging, is to pick topics that you do not have to go out of your way to find content about. Pick topics that affects your everyday life in some way or another.
