According to a 2015 Product Hunt Q&A, one of the ways he handles it is by building "a lot of consistent routine" into his schedule, so he can react effectively when something unexpected happens. For example, every morning Dorsey wakes up at 5 a.m., meditates for 30 minutes, and completes a seven-minute workout three times.
