My Things are a combination of my ideas and activities that other people have suggested. I'm not sure who to attribute today's Thing to; I tried to take a three-minute shower.
It usually takes me between seven and ten minutes to finish up in the shower, depending on if I have to shampoo my hair or not. I linger longer in the winter because the hot water feels good and I know it's going to be cold when I get out. Sometimes I let the water run while I clean the grout between the tiles, so I'm in there for a very long time.
It takes about a minute for the water to heat up in my shower; I decided not to count that time in my budget. When the water was hot, I looked at the clock to see what time it was, got in the shower, and closed the door. My hair wasn't dirty, so I just got it wet while I soaped up with shower gel. After my body was rinsed, I turned the water off immediately. I didn't linger at all.
I grabbed my towel and quickly dried off. When I was finished, I exited the shower, put my glasses on, and checked the clock. It was four minutes and ten seconds since I had entered the shower. Deducting the time I spent drying, I believe I reached my goal!
I don't know if I'm ready to completely give up my leisurely shower, though.
