From an NPR story remembering Tom Clancy:
Clancy didn't mince words when he talked to would-be writers. "If your objective is to write a book, get a computer and write the damn book," he told members of the military at a 2004 writing workshop. "Yes, you can do this if you try hard enough. It's a lot easier than you realize it is."
Seems like good advice to me. I already have the computer. Now I just need to "write the damn book."
RIP Tom Clancy.
