The way injustice often undermines our agency is by shrinking the horizons of what we think is possible. We simply accept that things cannot be any other way than they are.
This type of thinking is what i have strive to avoid, i know the systems set in place can be changed, and i understand it start with yourself. You change yourself, so you can change the world, is a literal statement, changing our mindset of complacent and full acceptance is the first step too seeing how things can be different for the better.
