Hey there! I've been recently disciplining myself to sit down nearly everyday to work on my comics for at least 15 minutes at a time.
That's been doing pretty well, especially now that I have a kitchen timer to get me started 
The funny thing is, because comics are a fun hobby for me, I can't stop once I start! 
I like that I can get in the zone and the boring stuff gets done more quickly(blegh coming up with ideas), but I feel like I kid who doesn't want to stop playing. Before I know it, I'm super late for bedtime XD
My next step in discipline is STOP drawing so I can go to bed on time.
How many of you have been trying to discipline yourself? Any unexpected challenges?
