The other card stuck to my monitor is a reminder to be mean.
I have a tendency to be way too nice to my characters, because I grow to love them, I guess. So this quote keeps me honest, that is true to life which does not play nice.
Happiness is good for the body but it is grief which develops the strength of the mind. -- Marcel Proust
You can probably find a quote a propos of anything in Proust, he was so wordy. I like this one because it gives weight to grief, a positive effect for suffering. When I suffer myself I try to remember this!
Speaking of suffering, I am reading my friend Gabriel Cohen's book, "Storms Can't Hurt the Sky," about his journey through Buddhism and divorce. You don't have to have a rocky marriage to get much from the book. Highly recommended.
