The best way to get better is to be honest with yourself. But honesty directed at you is painful. Responsibility doesn't leave you with an "out".
The sooner we address pain, the less it hurts and the more useful it is.
Open the painful email, look at the scary quarterly numbers, figure out that scary accounting balance nonsense and most of all look at yourself honestly and see what you can do better moving forward.
Before you find your purpose or the purpose of your company, you must be able to be honest with yourself.
