Value:

You want to create something of real value. But doing so is hard — it’s a complicated and demanding task.

Most people don’t end up making significant or outstanding contributions to their field of work or to any other area of human endeavor.

The middle range is where most real life happens — work that is useful, competent, and socially valuable. It keeps the world running, even if it rarely becomes historically remarkable.

Just to mention a few commonplaces here ...

Some people invent machines, others build and repair them, and others use and operate them.
