Create more value than you extract
I love this quote from David Hobby (aka Strobist). I like to think of it rephrased and focused on helping people. I think of it as “How can I help my friends? What can I do that they can’t do, that will make things better for them?”
David talks about “Manufactured Opportunities”. A project that you initiate, that you create. One where you take your skills and use them to give someone else something that they can’t give themselves. The rest of his Ecosystems 101 explains how that’s beneficial to you too.
