I met Simon Woodroffe once, the founder of Yo Sushi! and a thoroughly nice chap.He was in a similar position, doing jobs that paid the bills but didn't feed his mind. He says he knew, just knew that he had to be an entrepreneur but didn't know what he wanted to do.He bought a notebook and wrote down everything that he saw that he thought was cool, different, exciting. This ranged from products, services, jobs, design.The coolest thing he saw was a sushi restaurant which had the dishes moving around on a conveyor belt.He had no food industry experience.Simon's businesses and brands are now valued at over £1bn .Get out there, open your eyes and have the balls to make the leap!And remember this advice in your memoirs!!!
