Practice · one small step when you can't get going
You'll look at your mood and your week, pick one small thing, and set when you'll do it.
When mood is low, we naturally do less: cancel plans, go out less, drop things we used to enjoy. The trouble is that doing less also means fewer moments that feel good or feel like an achievement, and mood drops further. Behavioural activation works on the doing side of that loop: instead of waiting for motivation, you set one small activity, do it as planned, and notice how it actually felt.
In 1996, Jacobson and colleagues compared the parts of cognitive behavioural therapy and found that the behavioural part alone helped with depression about as much as the full treatment. Behavioural activation grew from that into a method of its own (Martell, Addis & Jacobson, 2001). This exercise keeps its core: notice enjoyment and achievement, connect with what matters to you, make the step small, plan ahead, and come back to compare.
This exercise doesn't replace professional care. If low mood has lasted several weeks, or is affecting your sleep, work or daily life, working through it with a counsellor or psychologist will take you further.
In therapy, people usually log their daily activities for a week or two before scheduling more over time; this exercise does a single round of it, so you can start any time.
