The illusion of control
The “close door” button on elevators isn’t connected to anything. Pushing it does absolutely nothing.
We often believe we have control over circumstances that we don’t. This can work against you. We might blame ourselves for outcomes which were never under our control. That’s just as true for the outcome of a product launch, the stock market, to how our children turn out. Of course you influence these things. But there are far more variables that lead to the outcome for you to assume full responsibility.
Next time you’re placing blame on yourself because of an unwanted outcome, try to look for the (many) other factors that have contributed to it.
