Merely write
Not ‘merely’ as in, sacrificing quality for quantity.
Not ‘merely’ as in just winging it.
But merely as in simply do it.
As in the only way around the inertia of ‘that’s no good, I’m stuck’ is to simply do it.
To take it one (bad) sentence at a time.
To merely show your work.
Because the only way to learn to write well is to continue to write (poorly) until you learn to write better.
