A suggestion when it comes to setting artistic goals: setting the goal "I'm going to make some sweet creative thing every night" is setting yourself up for disappointment. Because you're a human! No one is creative every single evening between the hours of 7 and 8p or whatever. And the pressure of having to do something "creative" makes you more stressed and angsty about it, and then all of a sudden doing this stuff isn't fun anymore and you quit. (Can you tell I'm sneaking in a therapy session for myself here? )
A goal that you can stick to, is "Every evening I'm going to sit down and spend 60 minutes making something in Blender. At the end of 60 minutes, I'll hit F12, save it, and post it, even if it sucks."
The pressure's off, the stakes are lowered... and yeah, sometimes the final result is pretty forgettable, but who cares? Sometimes you're going to hit F12 and it's going to surprise you with how sweet it looks. We don't always get to know in advance what's going to turn out good. Particularly as we're starting out, we've got to make a bunch of random crap to figure out how not to make good stuff. It's way more fun when you give yourself complete permission to try whatever comes to mind and if it looks like garbage, whatever. There's always tomorrow.
