 Burnout is the result of misalignment between the work that you're doing and your core values, your interest, your fascination, and the meaning behind your work. I don't know your daily schedule, but I imagine it's pretty immense. I imagine you work a lot of hours. But the reason you're not approaching burnout is you find meaning and purpose in those hours. You're being of service to millions of people. So that's why you don't experience burnout.
