Where do you do find motivation?

Where do you find motivation? I need some help finding mine because I seem to have lost it. I feel like I am a very motivated person, but lately it seems like I have been struggling trying to find any ounce of drive to workout beyond playing in the three volleyball leagues I play in each week. Im not sure what it is, or how it started but this little rut Im in has lasted for about a month and its starting to irritate me. So this is my question to the blogging world, what do you do when you need motivation and where do you find your inner drive to work out? My eating habits have been pretty good lately, but my workout habits have been MIA. I even went out and bought the new Jillian Michaels video: Ripped in 30, and nope nada. Im excited to do it, and I cant wait to see how much better it is than the shred....and its only a 20 minute video but nope, still cant find the motivation to do even a 20 minute video and Im usually a no nonsense just get it done type of girl.
