There are a lot of people with limited agency over their own work or personal lives, and are at the receiving end of other people's decisions.

Resentment can build when they perceive outside forces impacting their lives and personal well-being negatively. Sometimes this comes to define them as a person, in a self-reinforcing spiral of doom.

For most well adjusted people in decent work and social circles, we can take a more nuanced view, being both critical and optimistic as needed, and finding satisfaction in making the world work for us.

Consider yourself privileged.
