Some days are easier to see this quote properly. In other words, believe what it says. It's so easy to look at the negative stuff around us - even see negative in the good stuff.
For example, I was in a school meeting the other day. Progress reports just went out. A mom told the principal she was scheduling a conference with four teachers because her straight A student had received four "G"s instead of "O"s for his conduct in the classes. To me, she's off mark. And I hope I remember her if I start thinking that Good isn't enough.
I also think I will be happier if I stop thinking about what I didn't accomplish during the day. But instead, focus on the enjoyment what I DID accomplish.
What do you think?
