One of my first jobs out of highschool was as a cad drafter for an architecture firm. As the low kid on the totem-pole, I was given the tasks that were not liked by the architects: drawing detail sheets and reproducing blueprints. -- both tasks were highly repetative.

I took both as opportunities to find a meditative cadence to the work. I actually really enjoyed the rhythm of taking plots of large 30x42 inch drawings, marrying them with a blueprint sheet and sending it through the machine. The room was rather small - so you had to pickup a sheet, flip it over, rotate it, stack them, rotate the pair and feed it to the machine. It became a beautiful meditation in movement and was really enjoyable.

With details - I had to draw so many and build so many of the same sheets - I became exceedingly proficient and soon was an exceptionally fast cad drafter...

There is a lot one can learn through mass repetition especially if you do so with the right frame of mind - and not lament the task.
