When this applies
when defining any goal for a team, project, or personal ambition
The takeaway
The size of the goal you set is itself a lever on the size of outcome you'll achieve, and also the antidote to complacency.
Why it works
Large goals force out-of-the-box thinking and effort scaling; small goals cap ambition and produce small outcomes; achieving big goals also compounds motivation ('winning breeds winning').
One level up
Ambition is a renewable resource that must be deliberately re-fed, or comfort will default to stagnation.
Where it stops holding
This stops working when goals are so large they become disconnected from any credible action plan, producing demoralization instead of motivation.
Detail
rule: Always set big goals rather than small ones, in business and personal life.
threshold: e.g., compress a 3-year project into 3 months as an example of 'big'
rationale: If you set small goals, you achieve small things; if you set big goals, you achieve great things, and achieving them fuels further motivation, preventing complacency.
In their words
Set big goals, whether it's how much value you're creating, whether how much profits you're growing, whether a certain project that you think needs three years to get done and how you can get it done in three months.
