“The businessman who is able to calculate his risks – and then is willing to take them – has his battle for success nine-tenths won. The remaining one-tenth is the unknown variable, the unpredictable factor that puts the zest and excitement into the game. Without the ‘x’ factor, business would be hopelessly dull, routine and uninteresting.”
