"Some people profess difficulty at finding applications to write. I have never understood this: talk to people. People have problems — lots of problems, more than you could enumerate in a hundred lifetimes. Talk to a carpenter, ask him what about carpentry sucks. Talk to the receptionist at your dentist’s office — ask her what about her job sucks. Talk to a teacher — ask her what she spends time that she thinks adds the least value to her day."
