Oy, weekends are usually quite chaotic for me, and usually swap between - and very quickly swap between, at that - house chores, projects, personal projects, and family needs. There has been many a Monday where I've wondered, "WTF did I do this weekend?" and find I really don't know, because I did so much, but completed nothing!
Doing lots and completing nothing isn't so bad mate, it happens. It leaves something for the following weekend and that's ok too. I guess we're all different and relax and work at different rates and levels. You, to me, seem like someone who likes to get things done, or at least feel like you're moving forward, progressing. There's a certain comfort in that feeling right?
