Making your work visible:As Bryce described, this is indeed the fundamental starting point for working out loud.
Making work better: One of the main reasons for openly narrating your work is to find ways to improve it. You’re publishing so other people will see it, including some who can provide useful feedback, connections, or other things that will make your work better.
Leading with generosity: By framing your posts as contributions – as opposed to, say, efforts at self-promotion or personal branding – you’re more likely to engage other people. You’re not just looking for help but offering to help others, too. As Keith Ferrazzi said, “The currency of real networking is not greed but generosity.”
Building a social network: As you work out loud over time, you’ll be interacting with a broader range of people. The further you develop relationships with people in your network, the more likely it will be that you’ll collaborate with them and that they’ll be willing help you in other ways.
Making it all purposeful: Finally, since there’s an infinite amount of contributing and connecting you can do, you need to make it purposeful in order to be effective. (Goals might be as simple as “I want more recognition in my firm.” or “I’d like to explore opportunities in another industry or location.”) You can still have plenty of room for serendipity, but having a goal in mind focuses your learning, your publishing, and your connections.
