Own the next move even when you did not choose the previous one.

You do not have to have caused a situation to be the person who deals with it. Waiting for the responsible party to fix things keeps you passive in a life that is still yours, and sometimes nobody is coming. Taking the next move is not the same as accepting blame for the last one.

When you find yourself in a mess you did not create, separate the question of fault from the question of response. Handle the response. You can still say clearly that it was not your doing.
