- Boldness in itself is no guarantee of success.
- Boldness itself is no guarantee of success.
Firstly, I wrote a sentence (1), but then I wondered if the sentence also works without "in", as (2), because the reflexive pronoun itself emphasizes the idea of "without anything else added"
Two follow-up questions, are they able to occur at the positions?
1a. Boldness is no guarantee of success in itself.
2a. Boldness is no guarantee of success itself.
This "by itself for itself in itself" stuff kind of drives me crazy.
