What I know is I need management. Otherwise it's going to always be tomorrow and tomorrow (until there's no tomorrow). First I need something closer to normal business and non-business hours, which is extremely difficult for a freelancer, even when most clients are from one's own time zone. This will be doable only to a limited extent. Next, I need better management to make sure work is done before Sundays and important holidays and there's no need to work on such a day, ever.
As far as specific activities go — plans include walking and gym. The walking is to stretch out legs, get some fresh air, and get some basic minimum of fat burning and muscle use in case nothing better works out. The gym is for a number of reasons, including the fact that my asthmatic lungs and a backbone with 5 different diseases on it just simply don't allow any real nitty gritty fighting, especially protracted wrestling or getting thrown on things, so I need some quick Physical Dispute Resolution potential. This and deterrence. I'm already 6'5'' tall, so with some muscles on deterrence should be okay. On the other hand, people can simply get more aggressive when they see someone as big as this, and the way things are now I probably wouldn't stand much chance against a seasoned six-foot rogue who doesn't slave away in an office chair 16/6. Either way, I need more muscle. And less belly.
Plus, I need time for higher-quality reading than online news and articles about stuff. This means some magazines about history, psychology and law, perhaps some econ/biz.
And actually more gaming, rather than less. Facebook is the enemy, not gaming.
