I need motivation for mundane tasks, usually in the form of a deadline with real consequences. I will let dishes sit in the sink for days, leave clean clothes sitting in the laundry basket, etc, until someone tells me they are coming over and then I am running around like a mad woman cleaning things up. All of a sudden, I have motivation because I fear the embarrassment of looking like a slob.
Otherwise, I will look at those things and think, "I could do that, but first I will read for a bit, drink my coffee, check my email". I think it's very much a P thing to reward yourself first, and then do the task. When I become tired with "play" because it's not fulfilling me in certain ways or because the work hanging over my head is now interfering with my enjoyment, then I will attack the work. I get things done quickly and well when I am in the right frame of mind. If I try and force it, I am so lethargic and half-assed that it's not even worth trying. I got very good at my past jobs at faking looking busy while I really goofed off, and then I'd cram all the work in by the deadline successfully. And hey, I got it done, didn't I?
Inspiration is something I need for creativity (design in my case). It goes beyond the motivation of a deadline (which does help though). I need a muse. I can usually find it in other art forms, such as listening to music, looking at photography, etc. I also find I must clear my mind of practical worry so I can focus. I will go for a walk and look at the sky and trees. Then my mind is ready to create. It's a very good feeling to be in that place, but sometimes I cannot get there, or I get interrupted and can't find my way back.
I also have issues with doing things in my head first and then not wanting to do them in reality "again", but that's a different story...
