i always have buyers remorse after starting a new site with the name i pick. Now, i do keyword research first, then try for variations on those keywords. even better tho is a theme.

Because Every Action Has An Equal And Opposite Reaction, Measured In Pain...
This is the domain name and tag line for a new site (chronic pain related). for all categories in the site i will be able to do the xxxxx and pain, keep it flowing and probably some seo points in there too i.e. medication and pain or mobility and pain for various headings etc, see the theme? i wouldnt expect you to copy it, but im sure you can come up with something along those lines.
