I hate mine....it's a biblical name, but I'm not saying what! When I was a child in the '70s I wished I was American and told everyone my name was Emmeline (my middle name is Emma - don't like that much either, although it's a perfectly decent name, just don't think it suits me - and thought for some reason Emmeline sounded American!).....
Since I was about ten I've been known to close family/friends by a nickname that relates to a combination of my first and middle names - I always liked that, but the older I get (48 now), the more childish it sounds to me and yet I wouldn't want to revert to my 'real' name.
Annoyingly, cousins, aunts & uncles have always insisted on calling me by my much-hated first name, despite my signing cards with the nickname.....like they're rubbing it in......grrr!
Mind you, my parents' alternative choice for a name for me was Fleur - whilst that's more exotic, I don't think that suits me either.....
If I'd had a DD she'd have been Clementine Ivy (Ivy after my grandma), but we had a DS who has quite an unusual first name and an extremely rare middle name. He likes the shortened version of his first name, but hates his middle name!
