Try and balance your work with your leisure. The necessities with the optional. Give yourself incentives, like a carrot and stick approach but be realistic.
For example I might say to myself - First I'll start a new hub, get the idea off the ground, then I'll knock off and go sit with a drink, do something with the family, go anywhere else.
Once I'm satisfied I've got the hub under control I'll 'treat' myself and indulge.
Same principle with domestic stuff. My 93 year old mother needs her shopping done every week! I'm compelled to do that but I'll slot in some time for myself either the following afternoon or day.
Yeah I know it's tricky trying to fit so many things into a weekend - start with the basics and build up would be advice. Don't try to do too many things cos that's a surefire way of exhausting yourself!! Best of luck.
