It is brave of her to start her own business.
She is brave to start her own business.
Do the two sentences mean the same?

Question

Answer

Absolutely. Only the grammar is different. In the first sentence the subject is "it" = "to start her own business":
"To start her own business is brave".

In the second sentence, the subject is "she".

By making "she" the subject, the second sentence focuses more attention on her.

Answer

Yes, they have the same meaning!
