How about panicking that you'll be discovered as an imposter who has been slacking off and they will chop your body into tiny bits and then fire the bits?
For me, the main impediment is not a different hyper focus (bc my work is mostly fun and interesting to me, how lucky). The main impediment is overwhelm at the hugeness of effort or a Big Boring First Step.
Finding some route around that initial hurdle often breaks the dam.
