It's important for me to keep current - most of the things people quote and repeat (example: "people do business with people they know, like, and trust") are decades old - some from a previous century!
Last year I attended Content Marketing World in D.C. for three days - 22 breakout sessions and 9 keynotes - whew!
I use my Supernote to capture, and Voya's My Meeting Planner app to make sure everything is organized together, because I'm clear it's not attending that matters: it's bringing back current, usable information for PowerCore Members.
