I saw this on Dr Phil and we think it's BRILLIANT! When trying to choose a name, put it in these two sentences:
"I'd like to set you up on a date with my friend _________"
"I'd like to introduce you to your lawyer ______________"
If it doesn't work with BOTH of these scenarios, PICK ANOTHER NAME! In other words, it should be a name that is cool and fun, but can also be serious and professional. Love it.
