If you could put just one (non-commercial) quote, sentence, or idea on a billboard for the world to see, what would you write? This is a question that Tim Ferriss asks in almost all of his podcasts and I really like it. Some examples of quotes that I liked from his guests are below:
“Do your part” – Esther Perel
“You are the average of the five people you associate with most.” – Chase Jarvis (and Tim Ferriss, actually)
“Shut up and listen” – Brene Brown
“Nothing ventured, nothing gained.” – Richard Branson
On my billboard, I would simply put “Don’t be a dick.” To me, this is the source of all of the world’s problems and if people could follow this very simple instruction, we would all be much better off. It may seem extreme to say that it’s the source of all of the world’s problems, but I actually have trouble thinking of a case where this isn’t the solution. Racism, sexism, misinformation, bad worker conditions, hunger, inter-state wars, etc. Just don’t be a dick!
There is an argument to be made that the problems I mentioned above require more than simply not being a dick to solve. It might take going above and beyond the base level of non-dickishness to actually solve those problems in the long-term, but in my opinion almost every day-to-day issue that exists can be helped, if not solved, with that mantra.
This is actually a thing I’ve been thinking and trying to live by since I was around 13 years old. The mantra, to me, is the path toward living a just life and making the world a better place. So what would you write?
