When I first started my productivity journey I kept making habits, but then I realized some items can at once make me more productive.
Physical Alarm Clock
The reason I love this item is that its only purpose is to tell me the time and wake me up unlike the phone that has thousands of uses. I also like it when I keep the alarm far away from my bed, so I must walk to turn it off. It really wakes me up
Timer on desk
I have a little tomato timer that I use to time my focused work. The reason I like it is that it’s always in my field of view at my desk and that it takes seconds to start. Meaning it reduces friction to start doing focused work.
