There is a line often attributed to Viktor Frankl: between stimulus and response there is a space, and in that space lies our power to choose. Whether or not he wrote it in exactly those words, the idea carries his fingerprint. Frankl survived the camps and came back saying that the last human freedom is the choice of one's attitude in any given circumstances.
That space is usually very small. Something happens: a look, a memory, a message left unanswered, and we react before we have even arrived in the moment. The reaction is old. It was learned years ago, in rooms we may barely remember, and it fires faster than thought.
Therapy widens the space. Not by making us slower or more cautious, but by helping us see the reaction as it forms, the way you might watch a wave build before it breaks. Once you can see it, you have options. You can let it pass. You can choose differently. You can be curious about where it learned to move that way.
Yalom wrote that it is the relationship that heals. Part of what he meant, I think, is that the therapy room is a place where the space between things can be shared. When someone sits with you inside the moment you would usually rush through, the moment gets bigger, and you get more free inside it.
The space between what happens and what you do next is small, but it is yours. Widening it, even slightly, is how a life changes direction.
Between what happens to us and how we respond lies a small, quiet space. Therapy is learning to live there.
