I think the best way to frame this is not say that you don't want to work but instead that you want time to pursue some socially acceptable activity like "Learning Spanish", "Working on my haskell side software", or "Volunteering".

This makes you sound more like a high performer and less lazy.(I do not think people who want to work less are lazy. I would prefer to spend much less than 70% of my awake time involved in cranking out "yet another crud app". )
