Pretty much always.
comic-related: All of Chapter 0 was full of new things and I expect the same to be true of Chapter 1 that's upcoming. To start I'm putting a LOT more effort into backgrounds and architecture so that's going to be a real effort to do it right but I think I'm off on the right foot I've read Perspective for Comic Artists twice and I'm putting extra time and effort into everything regarding that.
Real Life: I'm learning a bit about couponing so I can do that with my girlfriend because she enjoys it. I'm teaching myself how to replace an ipad screen. And having a new baby basically everything is new and a learning experience with that. The whole thing is a series of experiments and trying new things.
Exercising is fantastic Remember 21 days to build the habit, 90 to make it a lifestyle just keep going no matter what. It's not a choice you're making. It's a part of the schedule for the day as much as eating, showering, brushing your teeth, going to work/school, etc...
