It's a lightbulb moment.
Make your brand your most important client.
Write your blog post before tweaking the 3 others you're ghostwriting.
Populate your twitter stream before logging in under your clients ID to make them a star.
Start that discussion on your Facebook page, change your profile picture and engage with your community before writing that killer social media strategy for anyone else.
Repeat until you stop feeling guilty (of course that could just be me).
