Ninety minutes after the kids are asleep is all I get and I've stopped pretending otherwise
There are a lot of posts here from people doing three hours a day. I get about ninety minutes on a good night, sometimes zero.
For a long time that made me feel like I wasn't serious about this. Then I did the maths — ninety minutes, five nights a week, is roughly thirty hours a month. That isn't nothing. It's just slower, and slower was never the same thing as failing.
The one change that helped most: I end every session by writing the exact next step, down to the file name. Saves the ten minutes I used to burn just remembering where I'd stopped.
