Reinvention starts when your explanation of who you were stops controlling who you can become.

You carry an explanation of who you are, built out of your history and repeated often enough to be automatic. It is generally accurate about the past and it quietly determines what you consider available now, ruling out whole categories before you ever consider them. Reinvention begins when that account stops being treated as a forecast. The past stays true; its jurisdiction shrinks.

Notice the sentences you use to explain yourself to new people. Ask which ones you are still choosing and which are just inherited. Try describing yourself once without the two that most limit you.
