Hmmm...

Have you ever heard this phrase?

Never regret something you once enjoyed.

Who said that?

That's not remotely true. I mean, imagine some guy like gets up in church to give a testimony, or some similar situation, and it goes like this:

"Well, once I was addicted to crack, but then God got a hold of my life, and today I am crack-free. However, I will never regret being on crack, because I enjoyed it. In fact, I enjoyed it a lot. Come to think of it, that was all I ever did. I miss being on crack..."

And then, he goes out and gets addicted to crack again.

Just because you enjoy something doesn't make it good.

Anything that isn't good is probably something you're going to regret.

And the only reason you're doing it is because you enjoy it.
