Interesting, but I personally find satisfaction with work and even work more hours a week because I spend some of my time socializing with my coworkers. If anything, working more makes me forget my life problems, when I'm not doing anything to distract myself I tend to start having dark thoughts, so better keep my mind active
In other hand I would like working less hours a day, 5 or 6, so I could engage in another degree or just finally start a graduation program. I wish companies have a more flexible work schedule on this sense
