Asking questions is more important than answering them.
You should ask questions when you know everything and when you know nothing. When you are alone and when you are in good company. When things go just as you planned and when nothing seems to fit in the right place.
We tend to think that confidence equals having few doubts and that experience means you are finally in a position to dispense answers.
In reality, confidence if feeling ok with not knowing and experience means you are faster at figuring out the questions to ask.
The world is upside down.
