100% I'm not a programmer by trade but I write tools for myself all the time. My favorite is a wiki-style knowledge base that I built for myself because I did not like the bulk or design of all the existing solutions. (I am a bit picky.) I use it every day for both work and personal stuff. There are lots of ways I want to improve it, but finding the time is difficult.
