I sometimes do and I did just a few minutes ago as I’m typing this. I decided 5 out of 7, whether or not I was going to go to a chinese buffet today. The coin decided 5-3, that I will. Then I wanted the coin to decide if I’m going thrifting today and with a landslide of 0-5, it didn’t want me to.
And do you stick to those choices?
I usually use it to make small decisions where I want to do the comparatively bad thing but I know I should be doing the good thing. For example, I slept poorly and don’t want to bike to work. Flip a coin to see if I get to take the train instead. I always do 3/5 as well.
