I recently saw a quote from Cath Crowley
“It's harder to make someone laugh than it is to make them cry.”
I immediately though she's wrong and then remembered making people laugh is an ability I've developed over the years of being an entertainer.
And then I stopped daydreaming and thought, you imbecile, you've been using comic scripts for so long, it's obviously become second nature to make people chuckle - even in the office!
Get a script, make people laugh, have fun and coerce people to liking you. Make the sales manager wonder in awe, how on earth you do what he can't.
