My two favorite messages of the week from October so far:
1. "Smile at everybody."
It's either catching, or incredibly annoying*. Either way, you feel great.
2. "Get a bunch done by lunch, and you're a winner by dinner."
A fun way to remember that starting the day strong can make all the difference. Implementation of this one has been a little tricky for me. So far the only way I've been able to make it work is by having lunch around midnight.
* They were stressing the infectiousness of happiness. I added the alternative benefit of driving grumpy people crazy.
