These videos have been all over the place recently, and I didn't want to lose track of them. If you've never heard Ira Glass's program This American Life on NPR I highly recommend it. I've spent many a Saturday afternoon working or cooking a meal and listening.
I especially like the third piece, where he talks about how important it is to create lots of work, in order to develop good work. In other words, don't quit when you're frustrated-- everybody goes through it. So get yourself a cup of tea (hot or iced, depending on your climate), sit back, and enjoy. And then get creating!
