Amos Dudley's blog about level design, environment modeling, and 3D.
My friend Zak likes to advocate the use of self-imposed consequences as a methodology for motivating oneself to action. For example, committing to burn (or better, donate) a thousand dollars if an important task isn’t completed. Monetary consequences are convenient because they easily scale to the importance of the task. I like this idea - especially if you have a friend who is willing to hold you to your commitments, usually by holding onto your money.
