Ray Bradbury on writing optimal behavior

"I don’t believe in optimism. I believe in optimal behavior.... You must live life at the top of your voice! 

"Action is hope. At the end of each day, when you’ve done your work, you lie there and think, Well, I’ll be damned, I did this today. It doesn’t matter how good it is, or how bad—you did it. At the end of the week you’ll have a certain amount of accumulation. At the end of a year, you look back and say, I’ll be damned, it’s been a good year."

 -- Ray Bradbury from a Paris Review interview
