Attention Is the Only Non-Renewable Resource and We're Strip-Mining It
You can earn more money. You can rebuild your health. You can make new friends to replace the ones you lost. Most resources that feel scarce can be regenerated if you invest the effort. Attention cannot. You have a finite amount of attention in your lifetime. When you spend it, it is gone. There is no getting it back. There is no earning more. You get what you get and then you die.
