Yesterday on a call my buddy Rem Jackson asked me: "Ben, how do you create so much content? I see new stuff from you everyday."
Here's the secret:
Just get in front of the video camera and start talkinga about what you know or about a question that someone asked you today. We've got a video studio built into our office and they aren't that hard to do. Your video needs to be good (hire a young tech savvy person!) but it doesn't need to be production quality.
Once you chat on the video someone else can take the audio from that and get it transcribed. Now, you have raw material that your team can re-pupose into blogs, website articles, letters to the editor and your own mailed (monthly) newsletter.
Honestly, this isn't that hard folks.
Its about systems.
