The Power Tank treats each major life role as a separate vehicle with its own energy reserve. First list the roles you occupy, such as parent, partner, founder, friend, sibling, or artist. Rate how much power is available for each instead of making one global judgement about your life. Before changing roles, pause and ask what the next role expects, what capacity you actually have, and what adjustment would close the gap. That may be a breath, a break, a modified expectation, or additional support. Finally, identify the recurring power robbers in depleted roles: the interactions, perspectives, or conditions that repeatedly leave you empty. The result is a targeted intervention rather than undirected guilt or the belief that weakness in one area means weakness everywhere.
Origin
Roberts describes life roles as cars parked in reserved spaces, each with its own tank. She uses the analogy when shifting from an interview to picking up her daughter.
Core principles
- 01Energy is role-specific rather than globally full or empty
- 02A weak area does not erase strength elsewhere
- 03Transitions deserve a deliberate pause
- 04Support should target the tank that is actually depleted
- 05Recurring drains reveal power robbers
How to run it
- 1
Map your vehicles
List every meaningful role you currently move through, such as parent, partner, founder, friend, sibling, or artist.
Pro tip Use roles that create distinct expectations rather than every task on your calendar.
- 2
Gauge each tank
Assess your available power separately for every role. Preserve the nuance that one role can be depleted while another remains strong.
Pro tip Use a simple low, medium, or high rating if numbers create false precision.
Watch out Do not label your whole life empty because one role is struggling.
- 3
Pause at transitions
Before entering the next role, ask how much capacity you have and what that role is likely to require from you.
Pro tip Attach the check to a physical transition such as leaving a meeting or arriving home.
- 4
Adjust the handoff
Choose the smallest useful intervention: take a breath, add a break, lower or communicate an expectation, or request support.
Watch out Do not promise an expression of energy you cannot sustain.

Find the power robbers
Look for what repeatedly drains a specific tank and change your perspective, engagement, or support around it.
Pro tip Track patterns by role so the remedy stays targeted.
In the wild
Roberts knows that after the interview she will pick up her daughter. She checks how much power remains for the version of herself her daughter expects, then considers the breath, break, or adjustment needed before that transition.
→ The role change becomes intentional instead of carrying depleted interview energy straight into parenting.
Professional difficulty can make an entire life feel as though it is failing. A role-by-role audit may show that the person is still an excellent friend, sibling, or artist, isolating the support need to work rather than globalising it.
→ Support targets the professional role while confidence in healthy roles remains intact.
Common mistakes
Using one global energy score
A single score hides which role needs help and makes local depletion feel like total inadequacy.
Skipping the transition
Moving directly from one role to another removes the chance to breathe, reset expectations, or ask for support.
Treating symptoms as robbers
Feeling tired is the signal; the power robber is the recurring interaction, perspective, or condition producing the drain.
Is it for you?
Best for
It is best for people moving among demanding family, professional, creative, and community roles.
Not ideal for
It is not ideal as a substitute for medical care or structural change when exhaustion is severe or chronic.
From the transcript
“these Reserve spaces are actually all the different hats that you wear”
“to be able to take a minute when we're transitioning from roles”
“the goal with the power tank analogy is to empower people to see their lives as something that is Broad but also Nuance so that…”
