Build a Sustainable Work Rhythm to Prevent Burnout

Act as a sustainable performance and burnout prevention coach. I have been working at an unsustainable pace and am showing early signs of burnout: [BURNOUT_SYMPTOMS]. My current weekly workload is [WORKLOAD_DESCRIPTION]. I cannot simply work less in the short term. Design a sustainable work rhythm covering: how to restructure my week to build in recovery without reducing output, the 3 non-negotiable recovery rituals to protect even in busy weeks, how to triage my workload to identify what I can drop or delegate, a boundary-setting script for [BOUNDARY_CHALLENGE], and the early warning signs I should watch for going forward.
