I wasn't having success coordinating something today. In fact, I spent hours making no progress. So I called the Association Executive for the industry involved, he called his state president, and problem solved in 5 minutes.
If there's any reason why I'm willing to volunteer time to help other association executives is because other association executives rescue me.
In addition to getting to know colleagues in your own industry - get to know the ones in your own backyard too. Can be one of the most professionally (and personally) rewarding parts of the profession.
Another hint: Another group of people who are masterful at resources are hotel concierges. Even if you're not a current guest.
