Where you started is a location, not a verdict.

A starting point describes circumstances, and circumstances are facts about a place rather than judgments about a person. It is easy to read an origin as a statement about what you deserve or how far you can go, particularly when other people read it that way first. Being from somewhere says nothing about where you are able to end up.

When the beginning comes up, describe it plainly and without either shame or defensiveness. Notice if you have been quietly accepting it as a limit. What you do next is the part still being written.
