I just whipped up a t-shirt design for Hustle's company summit happening in a couple weeks in Napa. When I have to design a t-shirt, I strive to design something that I would actually want to wear myself. Especially now that I work for a startup, since there seems to be a whole culture around wearing your startup-branded swag.
I used a quote that I've seen floating around, "Stay humble and hustle hard." In fact a number of people have suggested that they wanted it on a t-shirt, so this is their lucky day! Ideally I'd like more time for generating a breadth of ideas, but it serves just fine for such short notice.
I had fun manipulating some existing typefaces (Quicksand for the numbers, Heritage for the script, and Voster for the san serif) into an interesting composition.
