Never trust second thoughts. Next thing you know there'll be a third and a fourth...you'll be thinking forever.

Our reading
An editorial interpretation.
The speaker jokes that doubt is a slippery slope: one second thought invites a third, then a fourth, until you never stop deliberating. His advice to distrust reconsideration is tongue-in-cheek, poking fun at overthinking as a trap that keeps a person mentally busy forever.
