Mine is 2 fold. Here's my story.
Back in the day of hanging out with fellow Rick Springfield fans in chat rooms, most chose names relating to song titles. I chose lyrics that appear in several songs but one of my favorites in particular so I became BurningBright and it was hilarious. I'll never forget Bama going to a concert with me and looking at me with a raised eyebrow and saying "Now I know where your name comes from." IYKYK
I carried the name over into gaming as BurningBright until you Idiots made me a member and I had to change the name to accommodate the tags. Y'all nicknamed me BB and my kids thought it was cute and decided that my grandkids should call me BeBe.
The main reason for my name is this. Matthew 5:16 says "Let your light so shine before men, that they may see your good works, and glorify your Father which is in Heaven." This is my main goal in life and I can only hope to "burn bright" in this regard.
