Great question. I actually do read and write every day but publish 3 times a week. There are some pieces that have been in my draft folder for months and some that I will crank out that day, quickly edit, and publish. Topic wise, I have an Evernote notebook where I capture ideas throughout the day.
I feel like subject matter will always be a difficult thing to navigate, especially with topic I’m really passionate about. At this point, most of my friends make fun of me because “Let me guess, you’re going to turn that into an article” has become a regular thing.
