Build mastery
Do one thing every day that is challenging and leaves you feeling capable.
Why it works
Repeated experiences of competence build self-efficacy — the belief that you can handle challenges — which is one of the most reliable predictors of resilience under stress. In DBT, building mastery specifically counteracts the helplessness and worthlessness that negative emotion feeds, providing daily evidence that you are effective. The task must be challenging enough to feel like an achievement but achievable enough that it succeeds.
How to do it
- Identify something that is slightly difficult but doable today — not trivially easy and not overwhelming.
- Do it fully and notice the completion.
- Gradually increase the challenge as competence builds.
- Rotate domains: learning, physical, creative, interpersonal — different kinds of mastery feed different sources of self-efficacy.
Evidence
Building mastery applies Bandura’s self-efficacy theory, where mastery experiences are the strongest source of self-efficacy. Behavioral activation research also supports doing achievement-oriented activities to counteract depression and low mood. (observational)
The mechanism is well established; the DBT-specific prescription (daily challenge) is a clinical heuristic layered on top of it.

Common mistake
Setting the challenge too high so it fails, which reverses the effect — producing evidence of incompetence rather than competence. The level must be calibrated to succeed.

More practices for DBT Emotion Regulation Skills, Made Practical
- Understand the function of the emotion
Every emotion evolved because it does something useful — learn what yours is trying to do.
- Reduce emotional vulnerability (PLEASE)
Lower your baseline reactivity by protecting sleep, eating, exercise, and physical health.
- Accumulate positive experiences
Deliberately do things that generate positive emotion — building a reservoir that distress draws from.
- Opposite action
When an emotion doesn’t fit the facts or is unhelpful, act opposite to its urge — fully and wholeheartedly.
- Describe emotions nonjudgmentally
Narrate what you feel in plain, factual language — dropping "I’m terrible for feeling this."
- Mindfulness of the current emotion
Observe the emotion as a wave passing through — without judging it, feeding it, or running from it.
- Check the facts
Before acting on an emotion, ask whether your interpretation of the situation actually fits the evidence.
