I look constantly for the reasons that stop me from writing as much as I want; completing blog posts, editing, writing new stories.
Is it job pressure? Domestic duties pressure? TV? Reading? Depression? Fishing? Baking? Laziness?
Probably all of the above.
But the real killer is really simply not writing as much as I can, should, and most of all, want.
Fear the real killer. Face the real killer. Conquer the real killer.
Sit your butt down and write.
