What is your own operating system as CEO? How do you structure your time?

I see it as three buckets. The first is the main bottleneck I am personally obsessed with. That is the thing only I will work on because everyone else is busy running their trains on time. I want to carve out as much time as possible for that. The second bucket is all the reactive CEO work that fills your calendar. I try to compress that as much as I can. The third bucket is being a product CEO. I spend significant time with our engineering and product teams staying deeply familiar with what we are building. If I have a day that is completely packed from eight in the morning to six at night, I tell my team that was a wasted day. I did nothing to move the needle. I just worked for my calendar.
