The most obvious example of any of these principles I can remember would be the one on having a backbone. I used to work a production graphics job, just setting up whatever art file our customers sent us on table throws, tents, etc. One day, the art I received for an order was about black-on-black crime, some made-up statistic that would be going on a flag. I knew this wasn’t going to be used for anything other then racist messaging. The flag itself wasn’t overtly racist so while our company agreed to print the order, I did not agree to work on it and passed it off to my boss to do.
Invent and Simplify is also something I did several times at my previous job. We had these really long SOPs on how we were supposed to do our work. They could get really complicated and for new hires, it was a lot to sift through. So one day I took it upon myself to re-write them all concisely and clearly, showing examples. I also formatted several of our file types to be more of a template in nature, allowing other graphic artists to increase their speed and time spent on each order.
For thinking big, that reminds me of our mural class in college. The class was just about potentially designing something by taking a look at places on campus it could go and photoshopping our design onto our chosen spot. I went really wild with mine, and I spent a lot of time on it, more than any of my friends in class. In the end, I had this really cool geometric bluejay, made only out of triangles. I was really proud of it and my teacher and classmates liked it a lot also, and they petitioned the school president to put it up. Ultimately he didn’t because he was extremely conservative in terms of public art but it was very cool to see a big idea almost pay off.
As far as one’s I could stand to work on, I’d say most of the principles listed require some level of authority. I’ve really only ever had entry-level positions. I’ve never had enough power to voice my opinion and have any real expectation of enacting change. I think Frugality, Customer Obsession, and Are Right A Lot are things I could stand to work on when I find a job that I’m invested in and take the time to grow into a more senior role.
