Who made you smile? Additional thoughts, and smiles. :)

Keep a smile journal for 2 weeks. Who, what made you smile?
Tip: keep a 'smile journal' for a week or two, and try to write down every little thing that caused you to smile when you interacted with a product or service or person, and look for a pattern (or at least some ideas you can use). You can also track another person you interact with, and write down how often THEY smile, and what caused it. If the notebook is nearly blank at the end of two weeks, time to rent some Monty Python.]
So, who'd you make smile today? Who made you smile today?

Then apply these things to the things you make/create/etc for others. Even if you don't see 'em you can be responsible for making them smile. :)

Crinkly eyes = real smile. No crinkly eyes? Faker. (or too much botox)
Bonus: take this BBC quiz to test your ability to spot the difference between someone who's smile is genuine vs. a faker.
Perhaps the real question should not be, "Who'd you make smile today?" but rather, "How can you get yourself to smile more?" We all know it's true... real, genuine, authentic, natural smiles are infectious. Picture the people you know who can light up a room when they walk in with a big, REAL, smile.
