Patience. As long as I'm not buying something shiny, I'm generally pretty good at it.
When it comes to publishing stuff, however, all bets are off, and that's why I'm currently tweaking the snow and cloud coverage for An interlude v2. Somewhat ironically, those were the main two things I was disappointed in the Saraswati observatory, and consequently the reason I made the whole update-sequel-thing in the first place.
The upside of being able to render during weekends alone is, though, that I have more than enough time to make sure there won't be a need for v3. If I can resist the urge to install Fallout.
And there was snow. And fluffiness.
