I read about choice making or changing habits or something like that... there are many levels that prepare us for making change before we actually even seriously consider making a change. The first level is not even being aware that a choice or a change is possible. The second level is becoming aware of the choice but not being able to consider it as an option. The third level is like considering it may be an option, but it still feels impossible to make. The fourth level is considering that it might be possible. The levels after that are something like trying to think of ways to make it happen, then trying to make it happen but not yet succeeding, then it continues on to making the plan, going through with it and succeeding.
Progress along that path to change can be made at any time. Its a continuum. There is always hope, always a way out.
