Is there any ideas out there on how each type can motivate themselves?
For example maybe a Fi dominant could motivate themselves best by manipulating their values?
When discussing type, extraverted types will always need external stimulus to motivate them and introverts will be always self-motivated. An example would be that extraverts may be motivated to progress career wise to keep up with the Joneses (or a comparison to their neighbors) whereas introverts could care less about their neighbors and making external comparisons.
For a workable answer you should try asking this in edcoachings q&a thread.
Here's a simple way I help teachers explore how to motivate students. You can think of it in terms of dominant functions or take a look at each preference that applies to you and figure out which motivation might be easier to tap into in a given situation. I've got it charted by preferences, too, on how to finish a dissertation
Sensing--experiences that are physically real, useful and practical
Intuition--experiences that hold fascinating possibilities, engage imagination
Thinkingócontrol and competency, logical orderliness, things making sense

Intuition--make sure the dissertation has an exploratory, imaginative side. I used a metaphor throughout mine (It's actually called Long Underwear in the Tropics...
Thinking--pick something where you can be the expert or be in charge. A friend finished quickly by doing a case study of 4 competent female leaders, something she herself was
Feeling--make sure people are involved. Extend surveys into indepth interviews.
The 8 colors of fitness by Suzanne Brue emphasizes how to get motivated to stay physically fit by type but it'd be easy to translate the ideas into other areas of life
Working together by Isachsen and Berens, while very business oriented, lists characteristics and their implications. There is some info on motivations but I find it insightful in ways that motivates self-awareness that leads to wanting to change behaviors
What's Your Type of Career by Dunning looks at not just careers but HOW to job search by type and each type's pitfalls.
So a lot of what I think you might be looking for can be found within texts that have various applications of type theory. My whole book for teachers is in essence on how to motivate students--make them glad they're in class and actually learning something as well. Novel approach, huh...
