John works because he has to pay hi

John works because he has to pay his mortgage and feed himself and his family. He gets no satisfaction from his job and there is no chance of promotion. John’s motivators are purely extrinsic.
Sally works because she loves what she does, she gets enormous satisfaction and self-fulfilment from her work. Sally has enough money put away that she does not need to work, she owns her house outright and can afford to buy what she wants when she wants it. Sally’s motivators are purely intrinsic.
Clearly Sally and John are at different ends of the spectrum when it comes to self-motivation. Most people, however, fall somewhere in the middle.

Most people do have to work in order to earn money, but at the same time they also find their day-to-day work life rewarding or satisfying in other intrinsic ways - job satisfaction and the chance to socialise with colleagues, for example.
