Anyone have several book suggestions on improving one's mental fortitude and not being easily influenced by others despite what they say or think about you? I'm severely lacking in this area of my life as I can't easily say "no" to things I don't want to do – I fear what people say behind closed doors about me. I'm essentially known as a people pleaser and I want to change that about myself. If you have any non-book related suggestions (such as a motivational speaker or things of that sort), I'll take that too but ideally, I want book suggestions.
