I struggle to maintain focus, even on things I like working on. It’s worst when I’m blocked: I encounter a problem that I don’t fully understand, requiring at the a context-switch into some other documentation or a coworker’s help. Each blockage is an off-ramp to go do something else; I’d suddenly find myself checking my email, bothering an intern, or just playing with an easier project. Likewise, I’m introverted and dislike asking others for help, so I wait far too long to seek help when I get stuck — if I do at all. The net result is blocked projects stay blocked until I work up the willpower to work on them again.
