Hi
I think the best way to always have content is to relate your blog to your work. And based on this, always document what you do at work, try to bring what you do into writing mode and your work activities to make them easy to read documents for others. So you can even teach others about the discipline you practice. It is just what I do. My discipline is trading, so my financial analysis reports and what I do daily, I document and take it to people, so they can learn and use it to their advantage.
Cheers
Once Gary Vee said, document, not create. What he means that you documents your journey and what you do, that can be a good piece of content. It's hard to come up with content consistently. When you document, it just shares your jouney and speak your truth. Thank you @ale.aristeguieta for sharing your ideas about this.
