- intrinsic motivators: Achievement, responsibility and competence. motivators that come from the actual performance of the task or job -- the intrinsic interest of the work.
- extrinsic: pay, promotion, feedback, working conditions -- things that come from a person's environment, controlled by others.
Sometimes just having a new idea is motivation enough. It carries you through until you get it right and are happy with the result. This applies to both writing and craft work for me, I can become completely engrossed (and somewhat obsessive sometimes!) when I have an idea. The journey to that point can be where I lose momentum. From a writing perspective, sharing my work and getting feedback, whether online or in person, can give me that little boost I need.
My final observation is that, to be motivated most of the time, you need to stop and rest at least some of the time. Being constantly on the go and trying to produce quantity rather than quality can be draining and disheartening so don't be afraid to down tools, take a clean break and come back when you feel refreshed and invigorated.
