Stress
There's honestly not much stress at play here, unless you're working for someone who is exceptionally demanding and critical of your work. In that case, you may be asked to go back and undo/redo something you've been working on for the past week, which can be highly irritating and quite stressful.
If you know you're doing a bang-up job but the contractor you're working for is never satisfied or feels you aren't making enough progress—more stress. For the most part, however, you'll be left alone and it'll just be you, a machine, and the beautiful language you share. Doesn't sound too bad.
