I tend to work on stuff I want for myself after failing to convince less lazy, more capable people to do it for me. If I still want it enough to do it myself, then I do it. My impatience/random ideas and desires/tendency-to-criticize-everything must overcome my laziness to create a perfect storm to convince me I should actually fix some problem, that it's not just some random thing I'm being a perfectionist about, before I do anything.
