Identify your rocks before the day begins
Name your 1–3 most important outcomes for today — the rocks that must go in the jar first.
Key takeaways
- What it is: Name your 1–3 most important outcomes for today — the rocks that must go in the jar first.
- Why it works: Without a pre-identified priority, the day fills by default with whatever arrives first — email, messages, small tasks — which produce a sense of activity without meaningful progress. Pre-identifying rocks activates a goal-directed attentional filter (the implementation intention mechanism): the brain preferentially notices and routes toward cues related to the named priority. Naming 1–3 rocks rather than 10 forces the triage that allows focus.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Naming 7 or 8 rocks — which is a rebranded to-do list, not a priority filter. If everything is a rock, nothing is.
Why it works
Without a pre-identified priority, the day fills by default with whatever arrives first — email, messages, small tasks — which produce a sense of activity without meaningful progress. Pre-identifying rocks activates a goal-directed attentional filter (the implementation intention mechanism): the brain preferentially notices and routes toward cues related to the named priority. Naming 1–3 rocks rather than 10 forces the triage that allows focus.
How to do it
- 1Each evening or morning, write down your 1–3 rocks for the coming day — the outcomes that would make the day a genuine success.
- 2Each rock must be an outcome, not a process: "draft the proposal" not "work on the proposal."
- 3Rocks go on paper or a visible note — not into a task app where they compete with everything else.
- 4Ask: "If I only accomplished these 1–3 things today, would I be satisfied?" If yes, they’re rocks.
What the evidence says
RCT / meta-analysisImplementation intentions (Gollwitzer) reliably improve follow-through on pre-specified goals. Pre-identifying priorities functions as an implementation intention that primes selective attention toward goal-relevant tasks over the day.
Honest caveat: The rocks analogy itself is practitioner convention; the supporting mechanism is implementation intentions and goal-directed attention, which are well studied. The specific "1–3" cap is a reasonable heuristic for most job types.

Common mistake
Naming 7 or 8 rocks — which is a rebranded to-do list, not a priority filter. If everything is a rock, nothing is.
IX Coach prompts you to name your rocks at the start of each session and returns to them at the end, asking what happened to each and why.
