The fear that starting a business will inevitably mean an enforced period of belt tightening and dining on nothing but baked bean suppers has dissuaded many high flying executives from quitting their jobs to become entrepreneurs.

Far from earning less, those that quit corporate careers to create a start-up quickly make up any shortfall and are in fact earning more on average than their salaried peers just three years after completing their business school studies.
