Worrying or thinking about burnout would condition me to inevitably burnout. It doesn't really even enter my mind, because I know it will just make me and the business weaker. I simply look at it like: I want a successful business that gives me freedom to do what I want. Bootstrapped, staying small, and making money is the path towards that for me. I've been going 100% for 4 years, so I think if I were to ever burnout then that would have happened already. I take "workcations" somewhat regularly.
