Then as you monitor the automation you improve the scripts and your active involvement lessens over time, leaving more time for other things.
Maybe automate other parts of your job?
Self-improvement (training, education, experimentation, etc)?
Being available to consult or assist others, improving your "team player" metric?
Sell your ideas for automation, demonstrate the prototype (before it is perfected, of course)?
Entertainment? (Anything so long as it doesn't get you fired, which in a good company should be primarily based on job performance which is already covered, right?)
Just do it already...
