Workplace practices

[Tovius]

I work at an assembly line factory setting where I have a lot of time to just keep my hands in motion and not really think. I've used this time thr past few months to shut up my monkey mind and simply focus on breathing/binge listen to leo and other nonduality videos. 

I'm wondering though, is focusing on breathing the best practice for work? My main goal here is realizing nonduality through even a glimpse

What would you recommend? Maybe mindfulness of every movement, or just directly focusing on the task (which isn't necessary to do job correctly and well)? I also do a lot of Leo's enlightenment practices during work hours too, though that's obviously harder in a fast paced in motion environment.
