Lesson 17

Building New Habits: Stacking & Bundling

Recommended resources

Hello! Welcome back to our journey into the science of habits.

In the last lesson, we played the role of a detective, learning how to analyze and deconstruct any existing habit into its three core components: the Cue, the Routine, and the Reward. You now understand that to change a habit, you must first understand the loop that drives it.

Today, we switch roles from detective to architect. We will move from analysis to creation. This lesson is focused on a crucial practical skill: designing a new habit using two powerful, evidence-based strategies: habit stacking and temptation bundling. You'll learn how to engineer your environment and motivations to build routines that actively support your goals for high performance.

Strategy 1: Habit Stacking (Making the Cue Obvious)

The biggest challenge in forming a new habit is often just remembering to do it. Habit stacking solves this problem by linking your new desired habit to a pre-existing one that is already firmly established. The old habit becomes an undeniable cue for the new one.

The formula is simple and elegant:
After [Current Habit], I will [New Habit].

For example:

  • After I pour my morning coffee, I will meditate for one minute.
  • After I take off my work shoes, I will change into my workout clothes.

Let's watch a short video that introduces this concept.

How to become 37.78 times better at anything | Atomic Habits summary (by James Clear)

This clip from a summary of James Clear's bestselling book 'Atomic Habits' explains the core idea behind habit stacking.

Watch from 08:34 to 09:16. Focus on the simple formula presented and how it uses an existing habit as a trigger for a new one.

The power of habit stacking lies in leveraging the automaticity you've already built. Instead of relying on willpower or a reminder on your phone, you are piggybacking on a neural pathway that already fires every single day without fail. The cue for your new habit becomes as obvious and automatic as the established habit it's attached to.


Strategy 2: Temptation Bundling (Making the Routine Attractive)

While habit stacking solves the "remembering" problem (the cue), temptation bundling solves the "motivation" problem (the reward). Many important habits—like exercising, processing emails, or studying—aren't inherently enjoyable in the moment. Temptation bundling increases your odds of doing them by pairing them with something you genuinely want to do.

To see how effective this can be, let's start with a clever real-world example.

Temptation Bundling: A Simple Way to Boost Your Willpower

This article from James Clear opens with the story of an engineering student who found a brilliant way to make his exercise habit more appealing. It's a perfect introduction to temptation bundling.

Please read the first three paragraphs of the article, which tell the story of Ronan Byrne's 'Netflix-powered' exercise bike. This will give you an intuitive feel for the strategy.

The strategy Ronan Byrne used is an application of a well-established psychological concept called Premack's Principle. It states that "more probable behaviors will reinforce less probable behaviors." In simpler terms, you can get yourself to do something you need to do by linking it with something you want to do.

The following video provides a great overview of the science behind temptation bundling and how you can apply it systematically.

This video explains the psychological underpinnings of temptation bundling (Premack's Principle) and provides a clear, step-by-step guide to implementing it.

Watch from 00:37 to 05:19. As you watch, pay close attention to: The simple definition: grouping something you don't like with something you do like. The explanation of Premack's Principle and its evolutionary roots. The practical method for creating your own bundles using a two-column list.

This image provides a simple visual summary of how temptation bundling works to make a necessary but unappealing task more enjoyable.

This image compares 'Just Exercising' (low motivation), 'Just Indulging' (procrastination), and 'Temptation Bundling' (high motivation) to show how combining activities makes the necessary habit more attractive.

Combining Strategies for Maximum Impact

You can combine habit stacking and temptation bundling into a single, highly effective rule for building a new habit. This integrated approach not only tells you when and where to perform the habit but also makes it more attractive to do so.

The combined formula looks like this:

  1. After [Current Habit], I will [Habit I Need].
  2. After [Habit I Need], I will [Habit I Want].

The "want" serves as the immediate reward for completing the "need," making you more likely to look forward to the entire sequence. Let's return to the James Clear article to see how to put this all together.

Temptation Bundling: A Simple Way to Boost Your Willpower

This final reading will walk you through the practical steps of creating a temptation bundle and show you how to merge it with the habit stacking formula.

Read the section titled 'How to Create Your Temptation Bundle.' Focus on the two-column list exercise (your 'wants' and your 'shoulds') and the examples given for the combined habit stacking + temptation bundling formula.


Your Turn: Design a New Habit

Now it's time to be the architect of your own behavior. Choose a new habit you want to build to improve your personal performance. It could be related to studying, health, or a specific skill. Use the framework below to design it.

Step 1: Define Your New Habit
What is the specific habit you want to build? Be precise. (e.g., "Review my class notes for 15 minutes each day," not "Study more.")

  • New Habit (Routine): _________________________

Step 2: Apply Habit Stacking
What existing, automatic habit will you link your new habit to? This will be your cue.

  • Current Habit (Cue): _________________________
  • Your Habit Stack: After I _________________________, I will _________________________.

Step 3: Apply Temptation Bundling
What is a "want" or a guilty pleasure that you can pair with your new habit? This will make it more attractive.

  • 'Want' Activity (Reward): _________________________

Step 4: Create Your Combined Rule
Put it all together into a complete plan.

  1. After [Current Habit], I will [Your New Habit].
  2. After [Your New Habit], I will [Your 'Want' Activity].

Example:

  • New Habit: Tidy my desk and plan tomorrow's top 3 priorities.
  • Habit Stack: After I finish dinner, I will tidy my desk and plan tomorrow's priorities.
  • Temptation Bundle: After I plan my priorities, I will listen to my favorite podcast.

This systematic approach transforms a vague intention ("I should be more organized") into a concrete, actionable, and motivating plan.



Conclusion

In this lesson, you've acquired two essential tools for your performance psychology toolkit. You learned not just to analyze habits, but to proactively build them.

Key Takeaways:

  • Habit Stacking makes a new habit obvious by linking it to an existing habit. The formula is: After [Current Habit], I will [New Habit].
  • Temptation Bundling makes a new habit attractive by pairing an action you need to do with an action you want to do.
  • Combining these strategies creates a powerful rule that specifies the cue for your habit and builds in an immediate reward, dramatically increasing your chances of success.

Preview of the Next Lesson:

We've covered making habits obvious (the cue) and attractive (the reward). But what if the habit itself feels too difficult? In the next lesson, we will address the third law of behavior change: making it easy. You will learn to apply the 'law of least effort' to make desired habits easier and undesired habits harder, a crucial step for ensuring long-term consistency.
