Our intrinsic drivers are the things that naturally motivate us. Our choice of hobby often reflects what intrinsically drives us. When work is combined with this inner drive, our sense of job satisfaction increases. If we are lucky enough to work in our chosen field, intrinsic drivers are what get us out of bed in the morning.
