It's all grist to the mill

The thing about Harriet is, it wasn't about Harriet, ... To her, it was a matter of moving the grist through the mill. . . . She was a manager of the process.

God's mill goes slowly but grinds fine

To stand up straight and tread the turning mill,
To lie flat and know nothing and be still,
Are the two trades of man; and which is worse
I know not, but I know that both are ill.

Only a foolish woman would allow her man to earn his living as a moving target.

I?d describe them as run of the mill, not great but they?re not bad.
