ACT Therapy: What It Is, What It Is Not, and Why I Use It

If you have ever looked up ACT therapy and come away more confused than when you started, you are not alone. This is a question I hear often from clients across California who are trying to figure out if this approach might be right for them. Most explanations lead with terms like cognitive defusion, psychological flexibility, and the hexaflex model, and by the end you have a list of six core processes and no clearer sense of what actually happens in a session. This post is an attempt to fix that. Here is what ACT therapy is, what it is not, and how I actually use it in my work, which is not always by the book.

What is ACT therapy in plain language

ACT stands for Acceptance and Commitment Therapy. The core idea is straightforward even if the name is not: trying to get rid of difficult thoughts and feelings usually makes them worse, not better.

Most of us spend a significant amount of energy fighting our internal experience. Avoiding situations that might bring up anxiety. Trying to think our way out of something that keeps coming back. Telling ourselves we should not feel the way we feel. ACT asks you to try something different. Instead of fighting what is going on inside, you learn to make room for it and redirect your energy toward what you actually want to do with your life.

The two central questions in ACT are simple. What matters to you, and what are you doing that is getting in the way of that. Everything else in the approach flows from those two questions.

What ACT is not

ACT is not positive thinking. It is not about telling yourself everything is fine or reframing difficult experiences into something more comfortable. It is not about accepting bad situations without doing anything to change them.

It is also not meditation, though mindfulness is part of it. And it is not a rigid formula where every session follows the same steps in the same order.

In practice, I do not follow a strict ACT protocol. The framework informs how I think about what is happening for someone, but sessions are shaped by the person in front of me, not a set of predetermined steps. If you are looking for a therapist who will walk you through a structured ACT workbook week by week, that is not what I do. What I do is use the logic of ACT to help you understand what is getting in the way of the life you actually want, and work on that in a way that feels real rather than clinical. What that means in practice is that the work looks different for everyone. I am paying attention to your specific situation, your history, and what is actually getting in the way, not moving through a checklist.

The part about values, and why it matters more than it sounds

Values clarification is central to ACT and it tends to get glossed over in most explanations because it sounds abstract. It is worth spending some time on because in my experience it is often the most useful part of the work.

Most people come into values work thinking they already know what matters to them. Family, career, being a good person. But a lot of the people I work with have spent years moving through life on autopilot, doing what is expected at work, at home, with their kids, without ever stopping to ask whether any of it actually reflects what they care about. When you start asking more specific questions, like what does being a good partner actually look like in practice, the answers get harder. That gap between the general and the specific is usually where the real work is.

Values work is not about writing a mission statement for your life. It is about getting specific. What kind of partner do you want to be, not in theory but in practice. What kind of parent, friend, or colleague. What does it look like when you are living in a way that feels right to you, and what keeps getting in the way of that.

When those questions get more specific, decisions become easier and the things that felt impossible start to feel more workable. In my experience, clarity about what matters tends to make everything else more navigable.

What this looks like in an actual session

This is the part that is hardest to explain in the abstract, because no two sessions look the same.

One of the most common turning points is when someone realizes that the choices they have been making are not actually in line with the person they want to be. That sounds simple, but it lands differently when it is your own life you are looking at. Once your values are clearer, the choices that move you toward them become more obvious too. So does the pattern of choices that have been moving you in the opposite direction.

The other thing I pay attention to is goals. Goals should not be so difficult that you will not do them. Small steps that actually happen are more meaningful than ambitious ones that never get started. I help clients set goals that are realistic and achievable given where they are right now, not where they think they should be. Progress that you can actually feel tends to keep people engaged in the work in a way that distant or abstract goals do not.

Some sessions are mostly listening. Understanding what is going on, what someone has already tried, and where they keep getting stuck. Some involve a specific skill or a shift in perspective that changes how something feels. The ACT framework stays in the background orienting everything toward what matters, but the session follows the person, not a protocol.

Who ACT tends to work well for

ACT works well for people who have tried to think their way out of a problem and found that it does not work. People who are doing everything right on the outside but something still feels off. People who are not interested in spending sessions talking about feelings in the abstract but who are willing to think carefully about what they actually want their life and relationships to look like.

It also works well for people dealing with anxiety where the main obstacle is not a lack of insight but a pattern of avoidance that keeps getting in the way. And for people carrying grief or loss that has not had anywhere to go, where the work is less about processing and more about figuring out how to live fully alongside something that is not going away.

At its core, ACT helps you identify what actually matters to you so that you can start making choices that move you toward that rather than away from it. Most people I work with already know something is off. ACT helps you get specific about what that is and what to do differently.

ACT is not the right fit for everyone and it is not the only thing I use. But for the people I tend to work with, the combination of honesty about what you are avoiding, clarity about what actually matters to you, and practical work on changing the pattern tends to be more useful than approaches that focus primarily on insight or symptom reduction.

How I use ACT in my practice

I work with men, people dealing with anxiety, and people navigating grief and complicated loss, online across California and in person in the Bay Area. ACT is the primary framework I work from because it matches how I think about people and change. It does not ask you to become someone you are not. It asks you to get clearer on who you want to be and start closing the gap between that and how you are actually living.

If that sounds like the kind of work you are looking for, I offer a free 15 minute consultation. You can reach out here.
