I've gone to many conferences only walking away disappointed. I used to believe the main dish was the speakers, but you can only listen to so many people talk before being completely brain dead (and not remembering a thing).
What if you changed your approach? Instead, you planned who you wanted to talk to and what you will say when you converse with him/her. Consider a conference a place to "bump" into people intentionally and build your network. It's about quality, not quantity, so plan to continue the conversation after the conference has come and gone.
What do you think?
