Ergo my point about work and personal obligations (family, especially small kids). 2-4 hours per day for a solitary hobby is a surefire way to a divorce and estranged kids.
I'm married, kids, got an elderly parent at end of life that I'm caring for, and so on and so forth. How do I do it? Balance, right now, the kids are packing their bags to go to camp, so I have about 10 mins. I just replied to my prompt from last night, and will head out to drop them off, when I come in, I'll have a reply and enter my next prompt before I sign in for work. When the kids come in from school, they stay in my office and do their workbooks or watch TV while I sink in some work. You don't have to stay there for 4 straight hours, I get on the computer for 5 minutes, do a few and step out, then from that time till I get back on, I keep thinking about whatever problem I'm trying to solve.
