You said "whatever's easiest" again tonight, and you meant it about as much as you did the last time. Somewhere along the way, making yourself smaller stopped feeling like a choice and started feeling like your personality.
Unshrinking is about that swap: the apology that was never needed, the want you edited down before anyone objected to it, the opinion you scanned the room for permission to have. It isn't a confidence problem. It's a practiced habit, and it can be un-practiced the same way it was built.
Inside, you'll learn to hear "easygoing" for what it often is, a compliment people give you for making their life easier at your own expense. You'll trace the habit back to the room that first taught it, and see why that room changed but the habit never got the memo. You'll meet the borrowed inner critic that rewrites your sentences before anyone hears them, name it the Editor, and learn the test that separates real judgment from old programming. And you'll see what every unnecessary "sorry" quietly costs you in credit, title, and salary at work.
You'll also get exact words: what to say when the guilt shows up on schedule, when your idea gets repeated back in someone else's voice, and when you meet the people who liked you better small.
No personality overhaul. Just one unedited sentence at a time, in one room at a time, until your full size feels as automatic as shrinking used to.
You were never too much. You were practicing being less.
