I had to rethink how I phrased my answers. For one thing, I had to measure my effort. And to make it meaningful—that is, to see if I was trending positively, actually making progress—I had to measure on a relative scale, comparing the most recent day’s effort with previous days. I chose to grade myself on a 1-to-10 scale, with 10 being the best score. If I scored low on trying to be happy, I had only myself to blame. We may not hit our goals every time, but there’s no excuse for not trying. Anyone can try.
