This is a good answer, if not a directly helpful one if OP was looking for new slogans. One friend of mine has recently taken up Nix with a lot of enthusiasm, and by far the moments that have driven him forward the most were his own successes with his Nix-based projects. I've definitely hyped it up before in front of him, and I've definitely helped him along a couple times. But over and over, it's been actually using a capability that was new to him that got him worked up and excited to try more new things.
