Books for building vocabulary

[sanjukta_95]

Hello

Are there books you have read that could help build vocabulary of polite words/phrases?

I'm a person of  little words and refrain myself from speaking blunt truth. I feel the need to spill out often but lack of soft words impair my communication with myself and the world.

e.g. Words for people who 'register slowly'

Books by other introverts? By I

Thank you for the list.

It worked. That seems to be the only way.
