Old work, new work

While staring through the window and dreaming about my new novel (and doing some planning) I find images from my first novel stealing into my mind. I ask myself if that's because I'm afraid of stepping into the new or afraid of letting go of the old? I also find weaknesses in the first.

Just now, in this wonderful book by David Bayles & Ted Orland:
I found this:

New work is supposed to replace old work. If it does so by making the old work inadequate, insufficient and incomplete - well, that's life. (Frank Lloyd Wright advised young architects to plant ivy all around their early buildings, suggesting that in time it would grow to cover their 'youthful indiscretions'.) Old work tells you what you were paying attention to then; new work comments on the old by pointing out what you were not previously paying attention to.

How to make me feel better in just a few words.
