Several years ago I ran an experiment I called "Daily Derps". Every single day, I'd make a piece of audio, whether a new project in FLStudio, or a recording in Audacity (of my accordion, or some sound effect and whatnot). Then I switched to "Weekly Waaaghs", and my quality improved.
Now I know I'm not alone, so I'm resuming that old plan. I hope to learn from the brilliant Indie musicians hanging around here. :]
