Scattered, reactive, distracted, I was all over the place and jumping from one thought to the next. Everything was calling my attention. An email here, a quick check on Twitter there; I need some coffee right now. 😖
Love the Time Timer. I have been using it for almost a year.
I wouldn't rank it as an S tier for productivity hacks. Maybe like B tier depending on the context.
I don't find the 25-minute sprints great for my type of work. I usually do 40 min cycles or longer up to 1 hr 30 min max. It's usually either a -10 min task or a 40+ min one. Ymmv.
However, there's something ritualistic about turning the dial that helps get me into a competitive game mindset, which helps for reaching flow.
It definitely helps with time blindness as well.
