Be like the dog who cloaks himself in stink: Find joy and liberation in writing a first draft without caring, without giving one whittled whit. It’s like pouring paint on the floor or taking a sledgehammer to some kitchen counters. Get messy. Let it all hang out. Suck wantonly and without regard to others. Let that free you. Have fun. Don’t give a rat’s roasted rectum. You’ll think that all you’re doing is upending a garbage can on the page, but later, trust in the fact you’ll find pearls secreted away in the heaps of trash and piles of junk.
Amazing, totally true, advice on writing. This particular bit is applicable to every creative act. Just start.
