Right now my favorite presentation was by Lisa Leonard (http://www.lisaleonardonline.com/) and she made these points - again, applicable to business, my PTA position and life in general:
1. Find something you love and do that
2. Be genuine
3. Be consistent
4. It is good to have new and fresh ideas – be different
5. Take time out to relax, it will help get the creative juices flowing again
6. Listen to others with their honest feedback - you might be surprised at what others can see and how that can help you become a better (business, volunteer, person)
I will keep you posted!
