Dr Tim Carey, a controller, presents a perspective on the difficulty people experience in letting go of past events. He suggests that individuals often believe they cannot let go, but upon questioning, frequently reveal they do not want to. Carey posits that there is always a reason, however impractical it may seem, for holding onto these experiences. Understanding this underlying motivation is crucial, as letting go naturally occurs when the need to hold on diminishes. He emphasises that we are generally adept at letting go of unimportant things, and difficulty in doing so signals a continued significance attached to the issue.
