Episode Overview

In this episode, Jemma Sbeg explores the deep psychological roots behind toxic habits, particularly as they manifest in our 20s. She demystifies why breaking these behaviors is so difficult, dispelling the myth that it's solely a matter of willpower, and instead explaining how habits are wired into our brains as coping mechanisms. Jemma provides actionable insights, practical steps, and science-backed strategies for breaking toxic habits—whether they are as obvious as smoking or as subtle as thought patterns—while emphasizing compassion and self-understanding throughout the change process.

Key Discussion Points & Insights

1. Defining Toxic Habits and the 'Three Cs'

(03:18 – 06:45)

• Toxic habits are defined as repetitive, automatic behaviors reinforced by some form of reward but result in significant personal harm.
• Not every disliked habit is “toxic”—a habit crosses the line when the cost outweighs the comfort.
• Three Cs of Toxic Habits:
  • Compulsion: Urge to act repeatedly, often automatically.
  • Control: Struggle to stop or limit the behavior.
  • Consequences: Costs to health, time, relationships, money, or self-trust.

"A habit becomes toxic when the cost outweighs the comfort, when it starts to make your life smaller."
— Jemma Sbeg [05:42]

2. The Intention-Behavior Gap

(07:20 – 09:30)

• There's a gap between what we intend to do and what we actually do.
• Intention predicts only 30-40% of actual behavior.
• As habits are more emotionally charged, the gap widens; such habits serve to regulate overwhelming emotions, not align with values or goals.

"The more emotionally loaded a habit is, the wider the gap becomes between intention and behavior, because that habit is doing the job of regulating your internal emotions."
— Jemma Sbeg [08:44]

3. Emotional and Neurological Foundations of Habit

(09:40 – 13:30)

• Toxic habits often emerge as coping mechanisms for difficult emotions—stress, loneliness, boredom—especially in emotionally sensitive individuals.
• Neuroplasticity: Repeated behaviors strengthen specific neural pathways, making the habit automatic.
• Genetic factors (e.g., DRD2, COMT genes) influence dopamine regulation and can make some people more susceptible to habit formation and craving rewards.

"It sounds complicated, but basically your brain may just code certain behaviors differently and as more important or more worthy of repeating."
— Jemma Sbeg [12:45]

4. The Role of Upbringing & Emotional Expression

(13:50 – 17:08)

• If emotions were invalidated in childhood, people often turn to quiet, direct, and sometimes destructive methods of self-soothing.
• Habits formed early as mechanisms for coping with suppressed emotions can become deeply ingrained, even becoming part of one’s identity.

"When a habit becomes tied to your way of coping, to your identity, to your self, it’s harder to let go—not because the behavior is pleasurable, but because it feels familiar."
— Jemma Sbeg [16:32]

5. Common Mistakes in Breaking Toxic Habits & What To Do Instead

(22:18 – 29:30)

Mistake #1: Relying Solely on Willpower

• Willpower is finite and unreliable when emotions or life circumstances intervene.
• Solution: Have an alternative behavior ("Plan B") and adjust your environment to reduce friction for positive habits.

Mistake #2: Going Too Big, Too Fast

• Overambitious, all-or-nothing approaches like "75 Hard" overwhelm the brain and often result in giving up after setbacks.
• Solution: Set one small, manageable rule at a time and gradually build up success ("baby steps").

Mistake #3: Ignoring the Emotional Root

• Attempts to break habit by behavior alone fail if underlying emotional needs or fears are unaddressed.
• Solution: Ask reflective questions:
  • "What am I afraid might happen if I don’t do this behavior?"
  • "What is this habit actually trying to meet within me?"

Mistake #4: Self-Blame and Shame

• Harshness and shame are counterproductive.
• Solution: Self-compassion fosters the environment for sustainable change.

"Willpower isn’t designed to carry you long-term—it’s the spark, not the fuel."
— Jemma Sbeg [22:45]

"When the bar is set at perfection, the first slip-up feels detrimental...we abandon the effort—not because we're incapable of change, but because we’ve made the terms impossible."
— Jemma Sbeg [24:20]

6. Effective Strategies to Break Toxic Habits

(29:32 – 38:10)

Identity-Based Change

• Changing self-narrative is vital—behavior follows identity.
• Write down five “I am” statements that reflect the person who would not perform the habit.

"Behavior follows identity, not the other way around. When you begin to see yourself as someone capable of change, the behavior begins to align."
— Jemma Sbeg [29:45]

Mental Rehearsal

• Visualizing yourself resisting the habit builds neural 'scripts' and increases likelihood of success.

"Just picturing yourself being able to beat this habit...that is not wasted effort. You have a mental script to follow."
— Jemma Sbeg [33:18]

The Five-Minute Rule & Micro-Changes

• Start with resisting for just five minutes; incrementally extend your control to re-engage your conscious brain.

Valuing Delayed Gratification

• Set tangible, meaningful rewards at 1 week, 1 month, 3 months for not engaging in the habit.
• Experience how rewards feel sweeter when effort is invested.

7. Relapse and Self-Compassion

(38:25 – 40:40)

• Relapse is part of the process, not a sign of failure.
• True change comes with persistence, repeated attempts, and learning from “failures.”
• Compassion for yourself is essential—understand habits as survival strategies, not moral failures.

"If there’s one thing you take away—it’s that you cannot change anything about yourself if you do not change how you relate to yourself. And that is tender work."
— Jemma Sbeg [40:20]

Memorable Quotes & Moments

• On Willpower:
  "Willpower is the spark, not the fuel." [22:45]

• On Why We Can't Just Change:
  "You’re not choosing to vape, or overspend, or chase bad relationships because it aligns with your values...it might be the only way you know to regulate stress, distress, discomfort." [08:53]

• On Identity:
  "Behavior follows identity, not the other way around." [29:45]

• On Compassion in Change:
  "Relapse is not the end of the process...you do not unlearn a pathway in one quick motion." [38:30]

• On Delayed Rewards:
  "Train your brain and yourself that when you wait for things, they feel better...You will only learn this feeling through experience." [36:50]
