Productivity

Sometimes I struggle with being productive. But I think I figured out the trick. :) here's the story. I took on the responsibility of accompanying a piece of music for choir. I didn't get time to practice till about Tuesday. I thought it looked pretty easy so I wasn't too stressed about it. Little did I know... It's probably the most intense song I have ever tried to learn. So how do I get myself to practice? (More than I already have... Which has been about 15 hours this week...)
This is how.
