Post History

Some of the stuff you write is going to suck. Some of it is going to be without substance or inconsistent or just dull. And some of it is going to be brilliant in conception but dreadful in execution. 

The first you should junk. The second you should fix. 

But you won't always be able to tell which is which. This is what desk drawers are for. Stick the piece in a drawer long enough that you are no longer invested in the work you did, the effort you expended. Long enough, in other words, that you can throw it in the trash without a qualm. Then pull it out. If it is worthless, trash it. If you are still in love with it, or still intrigued by it, rewrite it. 

Repeat until published or trashed. (This could take years.)

The way you tell the difference between self-doubt and genuine fault is time.
