Great question. I think I've always assumed there is a connection between what you like and what you're good at, but you have a good example here too.

You don't say what you do love to do. That matters in this case, doesn't it? Is what you love a business possibility? If you love carpentry or business planning or cooking Mediterranean cuisine that's one thing, and if you love long walks on the beach or playing golf that's another. Although even there, people teach golf and start golf equipment shops, but you get what I mean.

Don't you like anything related to the advertising business? If you started these two businesses, do you have to be the one to do the selling? What about maybe doing the creative or the accounting or some other part of an advertising business, some part that you do love?

Everybody should be able to do what they love and get paid, but it doesn't seem to work out that way. There are only so many writers, artists, dancers, actors, and athletes with jobs. Then there are the teachers of writing, dancing, and acting, the coaches, and others who build businesses around what they love. And there are websites around what people like to do, and some of them make money. I apologize for not having a more definite answer, but thanks - you made me think about these things.
