You know some days when life seems to give you nothing but a bag of lemons and the last thing you can probably think to do is to laugh. But that's exactly what you should do.
A perfect example of this is Peter Parker, most of the residents of New York City hate Spider-Man, J. Jonah Jameson does nothing but dish out tons of hate towards the web-head and as Peter Parker he's continuously broke.
Nonetheless, he has enough in him to go out there and laugh. He tosses one-liners out at the crooks and villains and has Jameson at a loss for words with a few comical insults. He makes a choice to smile and enjoy the day even if it's all going downhill.
The challenge for today is to laugh as often as you can.
