When I was in High School, I figured out how to take the shortest shower possible. The secret is one of those things that is really simple when you say it, really simple when you apply it, but really hard to accomplish day after day. Letting my mind wander while hot water pours over my body is the only reason I can get out of bed quickly, and since there's no such motivation (except the clock or water heater running out) to get out of the shower I usually hang out for a while.
So what's the secret? Two things: 1.) Use both hands to clean at all times and 2.) Get out when you're done. People will have other tricks like top to bottom washing or soaping dry but really, if you can keep moving you will be clean in under 5 minutes. If you're clean, why are you staying in the shower? (Except girls who shave in the shower, I'm not going to complain :)
This turns out to be the basis of my strategy for getting things done in the new year. 1.) I need to always use all the tools at my disposal. 2.) I need to stop when I am finished.
So far I've blown through a bunch of things that otherwise would have been forgotten, or done at the last possible minute. I got my car registration done which required an oil change, emissions, check writing, getting stamps and mailing. I cleaned out my closet and will take 3 bags of stuff to good will once I also go through my dresser. I researched and got a new credit card. I'm more productive at work also.
In addition to getting a lot done, I've noticed that this is exhausting and I go to bed tired every night. But it is one of those good fatigues that makes you sleep hard and wake up refreshed. I'm making such good progress that I can soon start on something I really want to do verses these things that I needed to do.
