Hi purple planet,
you are probably missing the point about meditation. Labeling may be a good technique to start with and to gather a certain degree of mindfulness but you should come to a point where labeling is not necessary anymore. A more or less "bare" knowing establishes itself eventually where words even if only mentally spoken aren't necessary in order to know. Being mindful of being mindful of doing something becomes a self-sustaining feedback-loop. Instead of trying to find a job that is "easy enough" so that you'll still be able to verbalize what you're doing with mental labels is trying to avoid progress in some way. That way you're just treading water. There is a lot more going on in a split second than we are able to phrase in words. I recommend to start your meditation with labeling or with whatever you usually begin with and after developing a certain amount of mindfulness let go of labeling and try to just notice mindfully the same way you did before with labels. Notice but don't label what you notice, just notice. If you can't focus anymore on knowing start anew with labeling and repeat the process. How do you think one is mindful of speech for example? I don't think there is anybody able to label what he thinks, speaks and does all at once while talking. What I'm trying to say is, at the point where knowing replaces labeling it won't matter which job you'll do you'll still be able to uphold mindfulness.
I hope you get what I'm trying to say...
best wishes, acinteyyo
