To me, this reads like somebody who's surrounded by successful people who were already so ambitious they have converted their anxieties into more ambition. For every one of these Silicon-Valley-personality-type people, there are tens of others working menial jobs who are not in the 90th+ income-percentile who struggle leaving their house and have panic attacks at their part-time, hourly, no-benefits job who do not have this privilege of "disconnecting for mental clarity" or whatever else this blogger purports as the solution.

There are many better determinants for success than whether somebody has anxiety and is productivity-obsessed. The entire reason anxiety/depression/etc. are classified as disorders is because they disrupt well-being, which in the U.S. is largely measured by "ability to keep working in a job and stay alive". There are plenty of people with these disorders who aren't nearly as successful or ambitious, and plenty of successful and ambitious people who don't have an anxiety disorder. This association lies somewhere on the spectrum between "weird pattern I've noticed in my social bubble and decided is a near-universal law of nature" and "harmful misrepresentation of mental health disorders"
