Absolutely. To start with, I give a simple concrete suggestion in the first paragraph above about how to deal with physical pain. Another concrete suggestion might be: any time you feel annoyed or angry, express in words exactly what the annoyance or anger is like, using metaphors, and going back and forth between your words and your experience to make sure you've captured the experience in as accurate and original -- or non-cliched -- a way as you possibly can. A broader way to say the same thing might be: focus on those experiences that cause you emotional disturbance and express them, as accurately and as originally as possible, into an artistic medium of your choice (words, music, painting, whatever), using metaphors appropriate to that medium to convey what your experience is like. If you do that, my contention is that you will find that your negative experiences bear within them a wealth of beauty. There's more to it than that, but those are a couple of concrete suggestions.
