I was watching the Game Grumps recently, and they were talking about how they keep themselves busy in their crafts. Danny is a musician and Arin is an artist, like myself. They both discussed a method that was made famous by Jerry Seinfeld, called "Don't Break the Chain"
Basically, you keep a calendar near your workspace, and you make yourself work on your specific craft for a certain amount of time. Once you do, you mark the day off. Take the time to practice a little. No excuses.
A small calendar is now hanging over my workspace, and I'll be posting a drawing or more every single day, from now on. Period.
This first drawing was done in an hour and a half or so, on Mischief.
