A statement like that might seem to need qualifiers, but really, it doesn't.

I don't know what the hell I'm doing.

About very nearly anything.

Credo:
Strive to get more out of liking things than out of disliking things.

Commentary:
"More", in this context, means "enjoyment", "emotional investment" and "conversational contributions".

By and large, I think I've done pretty good in this arena. However, be advised: following this credo will often put you at a disadvantage in conversations with those who get their pleasure from disliking things, and finding fault and flaw.

"There is a crack in everything: that's how the light gets in."
