I slouch a lot too I feel like, especially when I'm drawing and hunched over my iPad or paper!
My worst habit though is sleeping in...but like really sleeping in and not getting up until past noon! For some reason if I don't wake up and get out of bed before say, 8am then I feel like the day's "wasted" so I might as well sleep more haha. It's probably because I sleep kinda late because I wait for my boyfriend to get done with playing video games with his friends (who are in a different time zone, so late at night is the best time for them), but I'm finally trying to get back to sleeping early. And not drinking coffee too close to bedtime.
