Best practice

When using "I thought once", ensure that the rest of the sentence provides enough context. Specify what you thought and, if relevant, why you no longer think that way or what changed your mind.

Common error

Avoid using "I thought once" when referring to a current thought or belief. This phrase is strictly for past thoughts. For current thoughts, use "I think" or "I believe".
