I apologize, quux. This form of communication is not easy for me.
There are many ways to motivate people other than money. Emotion is the key. In fact, people for a long time have come up with lists trying to identify the most basic motivators.
Here's one list:
Justice, Fortitude, Temperance, Prudence, Faith, Hope, Charity
Pride, Wrath, Envy, Lust, Gluttony, Avarice, Sloth
Money is such a great motivator because it is associated with many things in those lists. However, if you can associate things in those lists with something else, then you can use that as a motivator. Of course, you have to make sure that the things you choose are valued by the person you want to motivate.
Who's doing the motivating?
Good people, bad people, and everyone in between have used the method I've just described to motivate others. For me, the important thing is not taking money out of the equation or intrinsic vs. extrinsic motivation, but it's the relationship between the people involved. For example, let's say someone is trying to get money from you by appealing to your sense of charity. If it comes from a cult leader, it's creepy. But if it comes from a five year old chasing after an ice cream truck, then it's nice.
I don't know who you're trying to motivate, why, or what you want him or her to do, but I think it's more important to consider the relationships between people rather than the actual motivator itself. Does that person look at you as a hero, leader, parental figure, friend...? Or does that person look at you as a thief, cult leader, or worse, adverti...? Just kidding. Once you understand the relationships between the people involved, their values and the perceived risks, you'll have a better chance of choosing the right motivator.
I'm sure there are a bunch of other factors that must be considered in order to successfully motivate others, but for now, this is my limited understanding of the topic.
