1 hour each morning when your mind is the sharpest and most ready is so much more valuable to me than 3 hours late at night when i am tired from the work of the day
I mean it's ok and maybe even good if programming all day at work is enough of the thing you love before bed. You can do something else that makes artifacts like woodworking or Youtube videos or photography that's different.
It's ok and maybe even good to be multi-talented. Good luck.
Work on your project BEFORE the 9 to 5 job, not after. When you get home, rest and recover.
on the other hand when i watch something or play games something is growing in me which forces me to continue to work on my project.
i do have a lot of side projects and maybe half of them are "finished"
