The past is nothing more than the meaning you ascribe to it. Traumatic experiences can be changed. They are not fixed. Motivation is often broken into one of two categories: approach or avoid.

The events of your past are fixed. The meaning of your past is not.

The influence of every experience in your life is determined by the meaning you assign to it.

Assign a more useful meaning to your past and it becomes easier to take a more useful action in the present.

Everyone has a past, but that's just it — it's in the past. You can learn from it, but you can't change it.

The past is the past. Who or what we used to be doesn’t matter anymore. What matters is who and what we are now and who and what we can become in the future.

You can’t change your past, but you can change your story about it. What is important is not what happened to you but what you did about what happened to you.

It is a mistake to think that the past is dead. Nothing that has ever happened is quite without influence at this moment. The present is merely the past rolled up and concentrated in this second of time. You, too, are your past; often your face is your autobiography; you are what you are because of what you have been; because of your heredity stretching back into forgotten generations; because of every element of environment that has affected you, every man or woman that has met you, every book that you have read, every experience that you have had; all these are accumulated in your memory, your body, your character, your soul. So with a city, a country, and a race; it is its past, and cannot be understood without it.

The past is more than a memory.

The past is just something that's over.

Only by acceptance of the past, can you alter it

You think your past defines you, and worse, you think that it is an unchangeable reality, when really, your perception of it changes as you do.
Because experience is always multi-dimensional, there are a variety of memories, experiences, feelings, “gists” you can choose to recall…and what you choose is indicative of your present state of mind. So many people get caught up in allowing the past to define them or haunt them simply because they have not evolved to the place of seeing how the past did not prevent them from achieving the life they want, it facilitated it. This doesn’t mean to disregard or gloss over painful or traumatic events, but simply to be able to recall them with acceptance and to be able to place them in the storyline of your personal evolution.

The good, the bad, the ugly, and the pretty, it all adds up to me. I honor my journey, all of it. Changing the past would mean changing me. And I like me, just the way I am. Why would I want to change anything? Depending on who asks the question, I occasionally throw a curveball with a deeper, more philosophical answer, along these lines: I’ve already changed my past, by turning poison into medicine, and by raising my life condition, which transforms my perception of the past. Our perception determines the way events affect us. So, when we change the way a past event affects us, we effectively change the past. In other words, since past, present, and future are seamlessly connected, a change in the present moment has the power to affect a change in everything throughout all directions of space and time. Every now and then, when I share this answer, I’m told that I sound like a Jedi master from Star Wars, so I don’t share it often. But I hope you enjoy hearing it.

You think your past defines you, and worse, you think that it is an unchangeable reality, when really, your perception of it changes as you do.

The truth is that the past exists no more than the future, even though it feels as though it does.

We must abandon completely the notion of blaming the past for any kind of situation we're in and reverse our thinking and see that the past always flows back from the present. That now is the creative point of life. So you see its like the idea of forgiving somebody, you change the meaning of the past by doing that...Also watch the flow of music. The melody as its expressed is changed by notes that come later. Just as the meaning of a sentence...you wait till later to find out what the sentence means...The present is always changing the past.
