You are writing about abstract concepts which is only possible for advanced writers to do very well.  I understand more or less what you mean but not fully.  

I suggest you give us a very simple version of the same text which will help us understand your meaning better.  Then, it will be easier to improve the version you have posted.

Michael Chambers, thanks for your comment. I am writting about what I am interested in, of course I cant do very well, because I am just learning. Anyway I got necessary corrections.

Stability is illusory. The condition "plateau" is absurd. We are constantly in motion. This is condescending banality obviously, because we are constantly getting old in reality. We can say even tougher, but it is not my style.
We are constantly changing externally and internally. These processes do not stop for a second. Even a second, as a unite of measurement, is big here. Processes are going on every moment. This set is seconds. The question: "To change or not to change?" could not arised from a reasonable person. Instead, "Do I have the attitude for these changes and how much?"
