"Stressors are information"
As Nassim Taleb says in his excellent book ‘Antifragile’, ‘stressors are information’.
That means that rather than just get stressed by them, you can use them to direct improvement.
For example, when ‘exceptions’ start to become common, it’s a sign that something in your system needs to change in line with the environment.
A good place to start is by asking “How could I pre-empt this situation?”.
