Every morning I listen to a radio program. From monday to friday, the program follows the same schedule so I know without having to look at any watch, what am I doing during my morning routine. I know at what part of the program I brush my teeth, or heat the water for the tea, or do my skincare or leave the house.

Since the program is well structured and punctual, my schedule for the morning is well organized, I don't skip any step of it and am always on time. Something extremely important for me as if my morning routine fails for whatever reason, the rest of the day is guaranteed to be a mess.

I also have a shower playlist. My showers last 3 minutes, 4 tops. Having a playlist of songs no longer than 4 minutes, makes me know if I'm on time or I should already leave the shower.

Also, as others recommended, earplugs for when you need noise reduction. I use the Loop Switch ones as I can switch control the level of noise reduction with a small switch on them without having to take them off.
