Accountability
The practice of taking ownership of your commitments and having a social or structural mechanism that makes follow-through more likely.
Read definition →Behavioral Momentum
The tendency for consistent small actions to make future actions progressively easier, as each completed repetition reduces psychological friction.
Read definition →Compounding
The process by which small, consistent improvements accumulate exponentially over time, producing results that are disproportionate to individual daily effort.
Read definition →Deliberate Practice
A structured form of practice that targets specific weaknesses with focused effort and immediate feedback, as opposed to passive repetition.
Read definition →Fresh Start Effect
The psychological phenomenon where people are more likely to pursue goals following temporal landmarks that feel like a new beginning.
Read definition →Goal Gradient Effect
The tendency to accelerate effort as you get closer to a goal, producing a natural burst of motivation in the final phase of any pursuit.
Read definition →Habit Loop (Cue–Routine–Reward)
The three-part neurological cycle — cue, routine, reward — that encodes automatic behaviors in long-term memory.
Read definition →Habit Phase
A stage in the lifecycle of a habit — from initial intention through resistance and rhythm to full automaticity — each with distinct challenges and support strategies.
Read definition →Habit Shield / Recovery
A mechanism that allows one protected miss within a defined window without breaking a streak, acknowledging that imperfection is a normal part of long-term habit maintenance.
Read definition →Habit Stacking
A technique that links a new habit to an existing one using the formula 'After I [current habit], I will [new habit],' leveraging an established cue to automate a new behavior.
Read definition →Identity-Based Habits
An approach to behavior change where habits are grounded in who you want to become rather than what you want to achieve, making the behavior a natural expression of self-concept.
Read definition →Implementation Intention
A specific plan that links a future situation to a desired behavior using the format 'When situation X occurs, I will perform behavior Y,' dramatically increasing follow-through.
Read definition →Intrinsic Motivation
Motivation that comes from internal sources — genuine interest, curiosity, personal values, and meaning — rather than external rewards or social pressure.
Read definition →Keystone Habit
A single habit that, when established, triggers a cascade of other positive behavioral changes through its structure and the identity shift it produces.
Read definition →Milestone
A specific, meaningful checkpoint on the path to a larger goal, providing a near-term target that makes progress visible and maintains motivation across long timelines.
Read definition →SMART Goals
A goal-setting framework requiring that goals be Specific, Measurable, Achievable, Relevant, and Time-bound to increase the likelihood of success.
Read definition →Streak
A consecutive count of days or periods in which a habit has been completed without interruption, serving as a visible signal of consistency and a source of motivational momentum.
Read definition →Temptation Bundling
A technique that pairs a habit you want to build with an activity you already enjoy, making the desired behavior more immediately rewarding.
Read definition →Time Blocking
A scheduling technique that assigns specific tasks or habits to fixed time slots in advance, transforming intentions into protected calendar commitments.
Read definition →Two-Minute Rule
A behavior change principle that reduces any new habit to a version that takes two minutes or less to start, making the entry point so low that skipping becomes harder than starting.
