Success standard?

Last night I gave a talk around the bonfire at the camp I'm currently engaged in (I'll write tomorrow about the... challenging... experience that was).

The talk itself was nothing more than alright. At least in my mind.

Others said it was really good.

So... Who is right? Was the talk a success?

Whilst the talk wasn't a shocker, I'm not convinced execution is an accurate marker for success. Delivery is a detail, not the bulls eye.

What does count is response. How did those listening respond and how did the Spirit of God use what was said?
