Oh, I can handle a good preach...let that sermon flow brother!
I do tend to tie unnecessary baggage around my ankles at times (especially with respect to writing). I've become a true believer in Dzogchen and mindfulness, which has helped. I'm not sure I want to let go of the guilt, but instead notice it as more external to me. I'm better now about "watching" it enter the picture, and then smiling at it as it passes by and carries on to infect its next host ;)
I think that is pretty much exactly what I meant by letting go of it.
