I find the effects of overwork to be quite interesting- a lack of space for self makes it impossible to perform actually life enriching behaviors such as retreats, meditations, socialization, and hobbies. This means there's simply no room for any other entertainment or enrichment beyond the most shallow/fast/addictive stuff - social media, twitter wars, the thrill of buying nice things.
(EDIT: I should emphasize why it's so interesting to me because people often overwork with the justification for life enrichment, but the actual act of overworking reduces space/time for life enrichment!
