When making important decisions, always look for the missing pieces. You may think you have the whole picture, but you’ll almost certainly be missing part of it.
This doesn’t mean you need to know every variable before taking action, but you need to know that you’ve cross-examined your ideas thoroughly and honestly.
Even after you’ve made your decision and embarked on a particular path, you should always remain open to new evidence.
The most honest thing you can say is, “I don’t know.” Because there’s so little that we do know. And much of what we know, we only know in part. Humility is the key to understanding.
