I was listening to the owner of numerous successful businesses as he discussed marketing strategies, and he said, “Make sure you sell what you’ve got. If you’ve got grey hair (or no hair at all), sell your experience. If you’re young, sell your energy.” He went on, but you get the idea.
Here’s what I would add: if you want to sell something that you don’t have, then go and get it. What’s great is, there are lots of ways to do this.
For instance, you can take a class.
Or, you can teach a class (it doesn’t have to be at a major university—consider doing a free seminar at your local library).
You can join a club. Or, you can start a club. Or a website.
I could go on, but you get the idea.
