Glick's path has not been without physical cost. Around 2008, while training at purple belt, he tore his meniscus — an injury that might have sidelined a less committed practitioner. The meniscus has since largely healed, though shoulder arthritis has emerged as a more persistent challenge, placing certain positions and ranges of motion outside comfortable reach.
Rather than treating these setbacks as reasons to step away, Glick has internalized a principle central to Danaher's teaching: that practitioners should be on the mat doing something every day, even when sessions need not be demanding. As Glick has described it, the philosophy resembles water slowly dripping on a rock — not a large chisel making abrupt changes, but consistent, incremental contact that gradually reshapes the surface. Presence takes precedence over intensity.
Danaher's observation that no one reaches black belt without accumulating some injuries reframed Glick's relationship with physical setbacks. A conversation with the surgeon who treated his torn meniscus reinforced this perspective: the surgeon noted that comparable damage occurs across many sports — tennis, basketball, racquetball, and golf among them — normalizing injury as a natural feature of sustained athletic activity rather than a unique liability of grappling.
