I don't. Especially with these timesink genres...my fave genre was always RPG, but am gravitating away from them as I just don't seem to finish them (I say as I am 60 hours into the Witcher 3 and bought DQXI). These days I get way more play out of arcade/racing games that can be played in short bursts or games that are more watchable (random value and depends on wife).
No idea how people with kids can do it. I keep hearing about how people need less sleep as they get older but that hasn't happened to me yet...maybe kids help with that.
I really struggle to find time to game during the week as schedule/workload fluctuates wildly...some days better than others, but generally if in a bit of a lull I just want to veg or listen to music or something. I can work from home some , but can't really peel away during hours to game without it getting annoying (I do try on PC every now and then). There really isn't time enough to do much during
life the week, we get home, generally try and work out or some yard/house BS, cook dinner, maybe watch a little TV then go to bed.
Weekends just get away from you, especially if into any sports or anything. Sports are a great way to waste a weekend, and is what the majority of people I know do.
I would love a four day work week SO MUCH.
