If your effort to outcome ratio is low, don't grind!

That's working hard, not smart.

Working smart is working with leverage.

You'll judge your own result based on how hard you worked, while everyone else will judge it based on the quality of the output.

If you're having low-leverage output, then you're set up to resent it.

You'll judge the result as being high-value and others won't, and it will feel demoralizing.
