That is half correct. :c) Other humans can certainly influence you - but you do get to curate what gets through and what doesn't. ^_~
As for peoples' ability to affect your life - again there is a degree to which they can - but a strong spirit on your own part can go a long way to resist that.
You are welcome.
That is what I meant, in the end I need to decide and control what I want to listen to and what can affect me!
