The 1OPS principle is the single principle that had the biggest impact in my entire coding career. I gave some hints about it in a previous post, but I was suggested that it might warrant a post on its own to go more in depth.

There is a single advice I would give to anyone writing software, and specially to great devs : Always optimize your code for your most junior developers. I agree that it is not a very popular advice, but it is the one that, in my experience, give the biggest bang for the buck.
