In a population of bacteria, some individuals possess a gene that confers resistance to a particular antibiotic. If this antibiotic is introduced into their environment, what is most likely to occur?
- The antibiotic will have no effect on the bacterial population.
- Bacteria lacking the resistance gene will die, while those with the gene will survive and reproduce. (correct)
- All bacteria will develop resistance to the antibiotic.
- The antibiotic will cause the bacteria to mutate, leading to resistance.

Study Notes
Introduction
- Small changes yield big results over time.
- Habits can either help or hurt you.
The Fundamentals: Tiny Changes, Big Difference
- Habits are the compound interest of self-improvement.
- Improving 1% daily accumulates significantly in the long term.
- Success stems from daily habits, not rare, major transformations.
- It is more beneficial to focus on systems rather than setting goals.
- Your systems determine your level of achievement.
How Your Brain Works: The Science of Habit Formation
- A habit is a behavior repeated enough to become automatic.
- Habits solve life's problems with minimal energy.
- Conscious thought is usually a bottleneck in the brain, making habit formation useful.
The Habit Loop
- Habits form through a four-step process: cue, craving, response, reward
- Cue: It initiates the behavior.
- Craving: It is the motivation behind the habit.
- Response: It's the habit you perform.
- Reward: It is the end goal.
- The brain processes these steps in order each time.
The Science of Reward
- Rewards satisfy cravings.
- They teach us which actions are worth remembering.
Building a Better Habit: The Four Laws of Behavior Change
- These laws help in building good habits and breaking bad ones.
- 1st Law: Cue
- Good Habit: Make it Obvious
- Bad Habit: Make it Invisible
- 2nd Law: Craving
- Good Habit: Make it attractive
- Bad Habit: Make it Unattractive
- 3rd Law: Response
- Good Habit: Make it Easy
- Bad Habit: Make it Difficult
- 4th Law: Reward
- Good Habit: Make it Satisfying
- Bad Habit: Make it Unsatisfying
- 1st Law: Cue
The 1st Law: Make It Obvious
- Begin with a habit scorecard.
- List daily habits, marking "+" for good, "-" for bad, and "=" for neutral.
Implementation Intention
- Planning when and where to perform a new habit increases follow-through.
- Implementation Intention Formula: "I will [behavior] at [time] in [location]."
Habit Stacking
- Build a new habit by stacking it on top of an existing one.
- Habit Stacking Formula: "After I [current habit], I will [new habit]."
The 2nd Law: Make It Attractive
- Temptation bundling pairs an action to do with an action needed to do.
- Joining a culture where the desired behavior is normal is beneficial.
- Tribe membership enhances motivation.
The 3rd Law: Make It Easy
- Reduce friction to increase the likelihood of performing a behavior.
- "Prime the environment" by preparing it to simplify future actions.
- Ritualizing the beginning of a process aids in achieving deep focus.
The Two-Minute Rule
- Start new habits in two minutes or less.
- This makes habits easy to start.
- "Read before bed each night" becomes "Read one page".
- "Do thirty minutes of exercise" becomes "Put on my workout shoes".
- "Study for class" becomes "Open my notes".
The 4th Law: Make It Satisfying
- Repeating a behavior is more likely when the experience is satisfying.
- Missing once is an accident, missing twice starts a new habit.
- Get back on track as soon as possible.
- Habit tracking measures whether you performed a habit.
- Visual proof from habit trackers can be motivating.
- Progress is the most effective form of motivation.
Advanced Tactics
- Genes determine area of opportunity, not destiny.
- Professionals stick to schedules, while amateurs let life interfere.
- Excellence requires fascination with repetition.
- The Goldilocks Rule suggests peak motivation occurs when working on tasks at the edge of current abilities.
- Reflection and review promote honesty and self-awareness.
- Habits, combined with deliberate practice, lead to mastery.
