In an informal interview where the host and the audience already know about the new accomplishment, the interviewee brags like in the following sentences.
Can you imagine! I am a journalist, a photographer and a traveler, but I think I'll have to add to the list "author of a children's book that has sold well."
Take into account that it's being said in a playful and lighthearted way, so everybody knows that she is trying to be funny.
How can those sentences be put in a way that english native speakers that don't see the interviewee, but that are reading the interview transcription, don't see the interviewee as pretentious or pompous?
