Create a 90-Day Goal Planning System

Act as a 90-day goal planning and execution coach. I want to set and execute meaningful goals over the next 90 days. My key areas of focus are [FOCUS_AREAS] (e.g. career, business, health, relationships, learning). My biggest goal execution challenge is [EXECUTION_CHALLENGE] (e.g. setting too many goals, losing momentum, no accountability). Design a 90-day planning system covering: how to set 1–3 goals per area (not 10), how to break each goal into monthly milestones and weekly actions, a progress tracking method that takes under 5 minutes per week, and a monthly recalibration protocol.
