The Curio Viva
You wouldn’t buy your viva from a supermarket, assuming that the viva was a physical thing you could buy. You wouldn’t find it by wandering up and down aisles, past eighteen brands of pasta sauce and ten kinds of toilet paper. Supermarkets sell to everybody, and vivas aren’t for everybody.
You have to know where to look. You have to be a bit of an expert really.
You’d be more likely to find your viva in a specialist antique shop. These things take time to become what they are. They may be one-of-a-kind, expensive by now, and aren’t for everyone. They’re rarely looked for on a whim.
And your viva is certainly going to be one of a kind, a real curio.
Like my old salmon metaphor, there’s only so far you can go with this! Take away the idea that vivas are rare, and yours is just for you, and find your own metaphor to help you come to it with confidence.
