Hammond distils advice from his former Renault boss Tim Jackson into a timing rule for difficult choices. First ask whether the desired action is genuinely possible now. Then ask whether a later change in health, responsibilities, finances, access, or circumstance could remove that possibility. If the option matters, is feasible, and its downside is acceptable, the prospect of a closing window weighs in favour of acting. Hammond connects the rule to leaving a secure role for uncertain television work and to supporting his daughter's attempt to pursue equestrian work while he could provide a financial cushion. The method is not simply to follow every impulse. Its mechanism is to compare present capability with future optionality so that passive delay does not make the decision by default.

Core principles
- 01The ability to pursue an option can expire
- 02A failed attempt can be preferable to permanent uncertainty
- 03Current feasibility and future constraint should be considered together
How to run it
- 1
Define the option
State the meaningful action you are deciding whether to pursue.
Pro tip Make the choice specific enough to test for feasibility.
- 2
Test present feasibility
Confirm that the necessary access, capacity, and minimum support exist now.
Watch out Wanting an option does not make it currently viable.
- 3
Look for a closing window
Identify realistic reasons the opportunity may become harder or impossible later.
Pro tip Consider responsibilities and life stage, not just market deadlines.
Watch out Do not invent urgency to justify an impulse.
- 4
Bound the downside
Check that failure would remain survivable and would not violate essential obligations.
Pro tip Define the support, time, or money you can safely risk.
- 5
Decide before delay decides
If the action is meaningful, feasible, and acceptably bounded, pursue it while the window remains open.
In the wild
Hammond resigned from Renault for uncertain television work, briefly reversed the decision, then resigned again. He recalls Tim Jackson telling him that he had to pursue it while he could.
→ Hammond returned to broadcasting and later built his television career.
Hammond's daughter considered psychology at university but said horses were her real passion. Hammond told her that his ability to support her gave her a chance to explore it now, after which she could know she had tried even if it failed.
→ The available support turned uncertainty into a bounded opportunity to try.
Common mistakes
Confusing urgency with importance
A closing window matters only when the underlying option is worthwhile and feasible.
Ignoring the cost of failure
The rule should not override obligations or make an unaffordable downside acceptable.
Is it for you?
Best for
It is best for meaningful, feasible choices where timing matters and the downside has been considered.
Not ideal for
It is not ideal for reckless, unethical, unaffordable, or irreversible choices whose urgency is manufactured.
