How did you settle on a name?

I recently came to the conclusion that I was definitely supposed to be a woman (yay me). But I've spent the first half of my life trying to suppress that thought, that I hadn't put much thought into what I'd like to be called.

I'm trying to find a name which would suit a relatively butch lesbian with a mischievous personality who was born on terf island to boomer parents in the 80s but also works in Scandinavia. My given name has a female version, but it sounds weird for a Britt.

What made you settle on your names?

Edit: thanks for all the replies. I'm going to try out Kara for a while and see how it resonates. Feel free to suggest similar names or potential middle names (which absolutely should not start with k, by the way).
