You do not have to feel ready first

The trap of waiting for the right state

It is very understandable to wait. Wait until the anxiety settles before making the call. Wait until motivation returns before exercising. Wait until confidence arrives before applying for the role, having the conversation, going back into the world, or making the change that has been sitting there for months. From the inside, this can feel careful and reasonable. Why would you move while the mind is saying you are not ready?

The problem is that readiness can become a moving target. Anxiety often settles after we learn that we can carry it through an experience, not before. Sadness may lift partly because life has restarted in small ways, not because we waited until it had already gone. Self-doubt may become quieter only after repeated contact with evidence that we can act without complete confidence. When the rule is ‘I will do it once I feel right’, the feeling is given control over the size of a person’s life.

Psychological flexibility means room, not surrender

Acceptance and Commitment Therapy, or ACT, uses the term psychological flexibility for the capacity to stay in contact with the present moment and choose behaviour that fits one’s values, even when thoughts, feelings and body sensations are uncomfortable. That definition can sound neat, but in therapy it is usually very ordinary. It might mean noticing ‘I am going to fail’ as a thought, allowing the tightness in the chest to be present, and still sending the email because the relationship, responsibility or opportunity matters.

Acceptance does not mean liking the feeling, approving of what happened, giving up on change, or pretending pain is fine. It means reducing the extra struggle with internal experience when that struggle is becoming the main source of restriction. A person can be anxious and still behave with care. They can feel grief and still cook dinner for the children. They can feel ashamed and still speak honestly. Flexibility is not emotional toughness. It is a different relationship with what shows up inside.

What the recent research suggests

A 2024 systematic and meta-analytic review in Clinical Psychology Review examined psychological flexibility and inflexibility as possible treatment mechanisms in ACT. Across 77 records, covering 67 unique studies and 9,123 participants, ACT interventions tended to reduce forms of inflexibility such as experiential avoidance, cognitive fusion, inaction and lack of present-moment awareness. They also tended to increase flexibility processes such as acceptance, defusion, values contact and committed action. Importantly, those changes were linked with reductions in psychological distress.

That is useful, although it needs to be read carefully. Mechanism research is trying to understand how therapy works, and it is harder than simply asking whether symptoms changed. The authors noted that future studies need repeated measures, better multidimensional measurement and more effectiveness research in ordinary clinical settings. In plain language: the evidence fits the ACT model, but it does not prove that one process explains every person’s improvement or that flexibility can be produced by a script.

A 2025 BMC Psychiatry meta-analysis focused on randomised ACT trials for depression. It included 13 trials with 1,362 participants and found improvements in depression, anxiety and psychological flexibility compared with control conditions, with effects on depression and flexibility maintained at follow-up. The certainty of evidence ranged from very low to moderate, and many studies had risk-of-bias concerns, so this is a reason for cautious confidence rather than a guarantee. It suggests ACT can be helpful, particularly when therapy is more than positive thinking and is actually working with the person’s behaviour, attention and values.

Values are not inspirational slogans

In ACT, values are often misunderstood. They are not a vision board, a motivational phrase or a demand to become a more impressive version of yourself. Values are more like directions: how you want to be in the parts of life that matter, even when the conditions are not ideal. A parent may value steadiness, not because they always feel steady, but because steadiness is the direction they want to keep returning to. A professional may value integrity while also feeling scared of conflict. A person recovering from depression may value connection while still feeling flat when they first leave the house.

This matters clinically because many people come to therapy with a life organised around symptom management. The day becomes a sequence of attempts to avoid panic, shame, pain, conflict, exhaustion or uncertainty. Some avoidance is sensible and protective. Some of it quietly removes the very experiences that would make life feel worth the effort. Values help therapy ask a more precise question: if the symptom cannot be fully removed today, what would still be worth moving towards carefully?

When avoidance has a good reason

None of this means pushing through everything. Avoidance often has a history. A person who avoids conflict may have learned that disagreement was punished. Someone who avoids social situations may have been humiliated enough times that exposure now feels reckless. A person with trauma symptoms, chronic pain, functional neurological symptoms or burnout may have a nervous system that has become overprotective for understandable reasons. Good therapy does not shame the protection. It studies what the protection is doing now, what it costs, and whether there is a safer way to widen life again.

That is where formulation matters. The same outward behaviour can mean different things in different people. Staying home might be depression, recovery, fear of panic, pain pacing, grief, sensory overload, shame, or a practical need for rest. ACT is strongest when it is not used as a blunt instruction to ‘accept it and act anyway’. It should sit inside a careful understanding of the person, their risks, their relationships, their body and the pace at which change can be tolerated.

A more useful clinical question

The question is not ‘How do I get rid of this feeling so I can live?’ Sometimes treatment does aim to reduce symptoms, and there is nothing wrong with wanting relief. The more flexible question is: ‘What does this feeling usually make me do, and is that still working?’ If anxiety makes someone check, avoid, apologise, rehearse or delay, therapy can slow the sequence down enough to create choice. If sadness makes everything feel pointless, therapy can help build small forms of action before hope has fully returned. If shame says ‘hide’, therapy can test whether carefully chosen honesty is survivable.

A 2024 transdiagnostic day-hospital study found that increases in psychological flexibility during an ACT-based programme were associated with lower symptoms, better quality of life and improved functioning at discharge and follow-up. The study was not a randomised trial, so it cannot show that flexibility caused the improvements, and it involved a psychiatric day-hospital context rather than private outpatient therapy. Still, it fits a common clinical observation: people often improve when they can stop treating every painful internal event as an instruction.

For clients, the useful idea is gentle but demanding. You may not need to wait until anxiety, grief, doubt or low motivation has disappeared. You may need a careful plan for carrying it differently while doing one thing that matters. That is not a quick fix. It is often slow, specific work. But it can be the moment therapy shifts from trying to win an internal argument to helping a person re-enter their life with more choice.
