Is it that you don't "know how" or that you aren't motivated to do it? As I've gotten older (and overall more competent) my threshold for novelty / interest has gotten higher. Drudge work, that once might have been fresh for a younger version of myself, now feels repetitive. I already "know how" to do something, since I've done things like it before, and as soon as I sketch out the high level overview in my mind grinding through the implementation bores me. It's simply become harder to find projects I have an interest in. This manifests in my work. The stuff I find boring/lame I am terrible at - when I sit down to work, my mind wanders. For me, at least, this feels a lot like school. "I know this already. Or at least, I know the broad strokes enough that I can see how I'd go fill in the gaps. Time to zone out and think about something more interesting."
