Risk. At times I don't understand the word or concept. Truth is, we all need to take more of it.
When it comes to your program, look for the new, the different, the innovative. Don't be afraid to do fewer shows better or leave a show that you go to "just because we've always gone."
Try a new graphic. Or use a different staffing strategy. Implement an effective lead gathering approach. Push back on management when they don't understand a concept and want to change it because it's "different."
Explore new markets. Heck, explore markets in this economy. Make nothing out of bounds.
Lesson Learned: if you haven't done it, consider it; once you've considered it, do it; once you've done it, evaluate it.
