When inspiration for a great topic strikes, start writing feverishly. Ramble on as long as you like.
But when the time comes to create your blog post, step back and break it into chapters, or mini-topics. A short blog post about a narrow topic fares much better than an epic length fully-inclusive post. Especially if you want someone to actually read it.
Perhaps that is why I’m such a fan of Seth’s blog. I can absorb his message in a spare minute without missing a step in my daily agenda.
Bonus – you’ll have enough fodder to fill a topical blog series, and you can link between your mini-posts for a bit more SEO love.
