I had a hard time answering until I received a card from my coworkers at Goodness me. This I feel explains a lot of how I can justify living as I do :)
On the front of the card was a picture of butterflies inside a box. One of the butterflies had flown out of the box. The card read:
The Butterfly of Freedom
"Why do you fly outside the box?"
"I fly outside the box because I can."
"But we KNOW the box. We are SAFE inside the box!"
"That, my friend, is why I leave it.
For you may be SAFE... but I AM FREE!"
