I'm realizing that I, too, need to make some sacrifices in order to start pushing full steam ahead. Namely, I have to go out less. I spend a lot of time socializing. Some of it really nourishes me. Others of it feels like more of an obligation. And there's a whole range of things in between. So while I'll obviously try to keep the nourishing stuff in, and throw the obligatory stuff out, the overall result is that I won't be going out as much.
I think a reasonable goal is no more than one night out after work per week. And only one planned activity per weekend day. So if I plan to play tennis in the morning, then I don't also have people over for dinner that evening.
I have a sneaking suspicion that not only will I get more writing done, but I'll also enjoy life a tad more when I'm not running all over the place. And hopefully blogging about this plan will keep me honest about sticking with it!
