Decide Whether to Keep or Drop a Self-Improvement Goal

The goal made sense when you set it. Whether it still does is a different question this actually answers, weighing what continuing costs against what dropping it costs, then giving a clear keep, drop, or downgrade decision, with a smaller version on the table if that fits better.

<task>
**Help decide whether to keep or drop the goal:**
1. Ask what changed since the goal was set (circumstances, priorities, or just motivation)
2. Weigh the cost of continuing against the cost of dropping it
3. Offer a clear decision: keep, drop, or downgrade the goal into something smaller
4. If downgrading, suggest what a smaller, still meaningful version could look like
