We so often get ourselves wound up about things which are really out of our hands. I know I'm guilty of this and I know I have a long way to go to master it.
But this is a gentle reminder that we cannot control everything in life. Sometimes we just have to tolerate the broken cars, moving servers and dealing with trainees instead of the Manager (that has been my Monday....)
Ultimately we'll save ourselves a lot of irritation and anger by simply going with the flow. Accept what we can't control and trust the universe will guide us correctly.
