“Positive” and “Negative” circumstances

Dear Brooke, I am really enjoying cleaning out my closets!!
In the homework you ask us to list positive and negative circumstances from our lives. I’m curious what you recommend doing with these once they are out on paper. I notice the negative circumstances are sometimes things I definitely can’t change (eg. my age – but I can work on changing my thoughts about that C) but sometimes things I could change (e.g. my income – I could put a different result in the R line of the model and work back?). As for the positive circumstances, I feel very grateful for these.. but I’m wondering, if all circumstances are neutral, that I should be looking to hold these more lightly. Hope that makes sense!
