A person who thinks life is a buffet and they're eating every single dish. They're not smart. They're just dumb enough to keep going.
"I'll try skydiving. What's the worst that could happen?" (He didn't know he was going to fall from 10,000 feet.)
"I'll start a band. I’ve got a drum and a terrible voice."
"I'll get a tattoo. I'll regret it later, but it'll be worth it."
