Change

I been thinking about change this morning, and the old cliche comes to mind, "the only constant in life is change" and I think it probably is true, but I wonder if it is also true about the very essence of you, can you change after all you have seen, experienced and lived through, this sets patterns in your life, and I wonder if therapy could even change those ingrained patterns. Of course I will admit that all those things cause your growth, and that in essence is change, but after years of that growth there is a whole bunch of things that cause you to act, react, and feel, and that forms patterns of behaviour and I wonder if this can ever be truly changed or worst case scenario modified?
All that, got me thinking about just what I let into my life, and how those things are going to change how I act, and worst of all, will I repeat the errors I made before in the handling of these things because I haven't actually changed at all. The truth for me I'm afraid is dark, I am destined to keep repeating the same mistakes, I hear you all "the very fact that you acknowledge this is a step in the right direction"but this goes deeper that a step, these things are a lifetimes experiences, pushing, prodding, and moulding into a way of behaviour that for all the awareness in the world, I just can't help slipping into.
