My name is common as well. But I don't mind because I really like my name. but yeah it does get annoying when you share a class or activity with someone with the same name.
Because I'm pretty sure, that if I'm the only one with this name in a city with 500,000 people, it'll be hard to track down other people with the name 'Goldia'.
Almost everyone has that same name as someone else and those names are usually common so no. You are not the only one you are one of many with that. And it is similar in both the digital and real worlds.
Coming from the person with both quite uncommon names.
