From the moment you decide to change to the moment you feel the change, there is a period of progression.
You swing between the old and new, despite knowing, understanding, and feeling that the old doesn't suit you anymore, disturbs you, or even harms you. And despite that, you're still swinging between what once was and what you wish to be or wish to have. Progression is needed if we wish to survive. When I explain to a client how to solve problems with the AEQ method®, I often hear, "I've known a lot about this for a long time, but it hasn't helped me so far." To which I then ask, "Do you actually understand and comprehend this and actively deal with pain and problems?"
There is a big difference between knowing what needs to be done and learning from both successes and failures. We need to take our time and deal with change; conscious actions are required.
