Operating at this level requires adequate fuel. A slight caloric surplus or strict maintenance diet rich in clean carbohydrates (sweet potatoes, rice, oats) is required to sustain performance.
Harper kept the PDF on a thumb drive for years, not as a shrine but as a toolkit. The GBRS Performance Program, condensed into a clean, shareable file, had done something quieter than promising maximal output: it taught how to make small architecture changes that let people perform with presence and last beyond the next sprint. In the end Harper understood the slogan on the program’s back page — simple, practical, and militant in its humility: “Performance that endures.”
