I've found that doing all the non-work bits of advice helps, but it doesn't reverse the trend. It only slows down your burn rate which can be dangerous. You begin to think it is under control when in reality, you're like a frog in a pot slowly being boiled alive.
To really combat burnout, large influential companies need to target these types of articles at companies themselves, not individuals. We are beyond the point of calling out individuals. Notice how all of the language in this article (until #8) is centered around you. You are supposed to take full responsibility for burnout. It is your choice. Your lack of self-management is causing your burnout. But sometimes, it's really not you. It's them.
I hope the community begins to realize that responsibility goes both ways and shifts the focus of these conversations onto companies. Don't put the entire onus of burnout on the employee. That is avoiding responsibility and too much of it can make it appear to be victim blaming. Start talking about how companies can change culture around this, train management to recognize it, and what it takes to make this a top-down effort instead of a bottom-up one.
A good start to this conversation can be: What does Atlassian (or your company) do to prevent burnout throughout their company?
