September means back to school for kids and adults. Sometimes to move further in your business, you may need to take a class or two. However, experience is often the best teacher. There is value in your years of experience and passion, and this fall you may want to teach a class instead of taking a class. It doesn't matter if you are an expert in knitting or networking, there is probably a place where you can teach.
Check online for continuing education programs at community centers, colleges, conferences, writing schools, senior centers, nonprofit agencies and see where can teach. Ask around or even consider teaching someone in exchange for other business services that you need.
If money is not an issue, consider volunteering you services and sharing your knowledge with others. Teaching is one the best ways to validate your expertise to others.
