Frustration can be a very powerful source of motivation. In Muhammad Imran Abdullah’s case, it was what spurred him to open Positano Risto, a halal restaurant in Singapore serving authentic Italian food.

“What I actually realised was as Muslims, when we travel around the world, we don’t have a Western food chain that caters to halal diets, so when we go to places like London, New York and Tokyo, we can’t walk into any Western chain restaurant and eat there,” he says.
