Good ideas grab you like glue. Like a crush you had in high school, or the hook in your favourite song. You can’t brush a good idea off your shoulder or flick it from your hair anymore than you can unremember your first kiss, or unfeel the thrill of butterflies in the pit of your stomach. Sticky thinking is powerful because it clings to you. And the longer you carry it around, the more it mingles with your thoughts, your feelings, the way you see the world. It gets shared around, forwarded on, put on TV, posted on blogs, walls and t-shirts. Sticky thinking changes how people think. Here at McCann Melbourne, we think it can change the world.
