Try and come up with a name that you think fits you, or at the very least something that isn't really common. Unfortunately, a lot of people fall back on Greek or Roman mythology for names (this is especially true if you look at the websites of pro-dommes).

I came up with my name on accident, but in a way I think it fits even though it doesn't really mean much of anything.

The best thing you can do is brainstorm. Only you can create your name. Start off by maybe making a list of interests, take out the good ole' thesaurus (or use the one online), and find words that you like together. You don't have to like anything you're writing down, but just write it. Sometimes the best ideas come from seemingly nowhere.

If you're making a list of interests, you can always try and list authors or poets you like, maybe make an allusion to literature you enjoy, or hobbies, or maybe something about how you see yourself.

Some ideas to consider for a blog name would be:
What will be easily remembered?
What is the purpose (and/or focus) of my blog?
Who do I want to read my blog?

Those are just some ideas for starters. Sorry if I sound like I'm just blathering on, but I hope maybe something here helped. Good luck and if you want, feel free to shoot me a message!
