You can have meaning, accomplishment, engagement and good relationships, even if you are dull on the positive affect side.
More Martin Seligman quotes :
Positive thinking is the notion that if you think good thoughts, things will work out well. Optimism is the feeling of thinking things will be well and be hopeful.Martin Seligman
I think you can be depressed and flourish, I think you can have cancer and flourish, I think you can be divorced and flourish. When we believed that happiness was only smiling and good mood, that wasn't very good for people like me, people in the lower half of positive affectivity.Martin Seligman
I'm trying to broaden the scope of positive psychology well beyond the smiley face. Happiness is just one-fifth of what human beings choose to do.Martin Seligman
