Tighten the screws

A friend wrote "tighten the screws" on his work desk.
As in: buckle down. Work harder. Make it happen.
This bit of graffiti reminds me of the same thing.
I've been playing a lot lately. Writing some, but not enough.
Taking pictures, and not doing much with them.
Not taking time to wander the city, to slow down and look around.
Something's scaring me and I want to confront it.
I can jump off a Zambian bridge but I can't confront my own timid mind?
Tighten the screws. Rejoin the universe of friends doing cool creative things.
