I. Read mediocre writing. If you only read good writing, you can't tell what makes it good; it just looks like all writing is good.
Doesn't anyone who spends a decent amount of time on the internet these days have a lot of contact with mediocre writing?
I think it works for fanfic. Certainly does for music. Some ideas, you don't realise how bad they can be without seeing.

Earning to Give Writing: Which are the places that pay 1USD or more dollars per word?
Mind Changing Writing: What books need being written that can actually help people effectively change the world?
Clarification Writing: What needs being written because it is only through writing that these ideas will emerge in the first place?

The world surely won't save itself through writing, but it surely won't write itself either.
