I just started with New History for the first time today. My question is....is it more beneficial to focus on one negative event from the past per session or is it possible to dredge up a few things every time to try to work them through?

I have a few things in my life that have bothered me and I feel has held me back. When I listened to the CD Paul suggested starting as far back as you can remember and walk through your life and remember things. Well there are a lot of negative things going on there! LOL! Should I just focus on one at a time?
