Good advice if you're already confident a number of things you find troublesome about your life cannot be resolved, such as if you've already gone through therapy or tried more focused interventions that have not worked. Sometimes you have to leap to the new platform, and its hard to see just how bad your context was until you've left it.
Question is what is the threshold for change, and are there 'blow up some things' changes that can be made prior to 'blow up everything'. Would love to see this in the form of a (How Much) Should I Blow My Life Up self assessment.
