Set specific, hard goals rather than "do your best"
Replace vague aspirations with a precise, stretching target — this is the core lever.
Key takeaways
- What it is: Replace vague aspirations with a precise, stretching target — this is the core lever.
- Why it works: Specific goals direct attention to goal-relevant actions and away from irrelevant ones. Hard goals mobilize more effort and persistence than easy goals because the discrepancy between current and desired state is larger, activating a self-regulatory loop. "Do your best" is effectively unregulated — there is no gap to close, so the regulatory cycle never fires with full intensity.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Adding a comfortable buffer — "I’ll aim for 90% so I still feel successful at 85%" — which converts a hard goal into an easy one and loses the performance benefit.
Why it works
Specific goals direct attention to goal-relevant actions and away from irrelevant ones. Hard goals mobilize more effort and persistence than easy goals because the discrepancy between current and desired state is larger, activating a self-regulatory loop. "Do your best" is effectively unregulated — there is no gap to close, so the regulatory cycle never fires with full intensity.
How to do it
- 1Name the exact number, deliverable, or observable outcome you are aiming for.
- 2Calibrate difficulty so the goal is genuinely challenging but not outside your range of ability.
- 3State the goal in writing before the work period begins.
- 4Avoid adding safety margins that quietly make the goal easy — the difficulty is the mechanism.
What the evidence says
RCT / meta-analysisThis is the central finding of Locke and Latham’s work. Their 1990 meta-analysis covered over 200 studies and consistently found that specific, hard goals outperform vague or easy ones on performance outcomes.
Honest caveat: Effects are strongest for well-defined tasks with clear metrics. For complex or creative tasks requiring extensive discovery, very specific goals can restrict exploration and actually hurt performance.

Common mistake
Adding a comfortable buffer — "I’ll aim for 90% so I still feel successful at 85%" — which converts a hard goal into an easy one and loses the performance benefit.
IX Coach pressure-tests your stated goal for specificity and difficulty, and pushes back when a target is vague or quietly lowballed — the discomfort is the point.
