“Whenever somebody asks you to do something a long time from now, change the framing and say, ‘What if it was tomorrow? Would you want to do this or not?’ Almost invariably, the answer is, ‘No, I definitely don’t want to do this tomorrow.’ And then you should answer based on that.”
— Luis von Ahn

“Hopefully, most people have seen the Duolingo owl. It’s our mascot. First of all, it’s an owl because in most Western countries, owls represent knowledge. Turns out this is just not true at all in Asia. Now that we’ve been expanding to Asia, people ask us, ‘Why the hell are you using an owl? Owls are just vicious animals.’”
— Luis von Ahn
