I have to agree with Fade, its pretty much common sense, I would like to see the rest of the presentation before casting final judgement.
He makes a few good points like ease of workflow and good preparation, and clear mind and some others I disagree with, like the keeping of a journal.
The best part I gleaned from the video is....
When creating music, avoid distractions that can interfere with concentration,
try not to over produce music, take it one step at a time. Work hard to push yourself, no one is really going to do it for you.
And yes mistakes can be your biggest learning moments.
