I used to think...that what I do is important. Now I know this is perhaps not half as important as what I do after I've done it.
When I mess up, it's what I do next that probably makes the most difference. When I do something really good, it's what I do next that is probably most significant.
In other words, it may be how I think about what I've done that most prepares me for what is next. Am I proud? A I humble? Am I wallowing in self-pity? Do I get up again? Do I understand why I do these things?
