So don't have a defeatist attitude all the time, but once in a while try to actually have an impact. We will all be much better for it.
...And everyone walking around with an attitude like that is exactly why the world is as shitty as it is. The world is the sum of all of us. Think better of yourself and your time, and do everything you can to make life harder for those that would try to sell you on cheapening it, and you just might make the world a better place for everyone.
Unless you're very wealthy, very violent, or very committed to a cause (often to the point of entering politics or raising/moving money) your individual contribution is negligible.
An uneducated mechanic and his wife decide to give an unwanted child a home, dad builds a workbench for his son and teaches him how to use tools to break, fix and build things, inadvertently setting in motion the beginning of Apple.
Sure, there were other events Jobs parents had absolutely no control over, like those that led Bill Fernandez to the same school as Jobs.
But it is undeniable that without Paul and Clara Jobs adopting Steve there would be no Apple and the world would look completely different today.
So through our small, individual contributions we can definitely nudge the world to follow a particular direction, and if enough people do it, it is expected that once in a while one of us actually ends up changing the world.
This is a bizarrely extreme form of black and white thinking, and not one I understand. Most of what we do in life isn't about changing the world, it's about managing our experience of it.
Few people are deluded enough or so engaged with self-love that they think their ideas and behavior are world-changing.
