You’re not as in control as you think.
Just because you’re more stressed and anxious about the outcome, doesn’t make it any more likely that it will work out how you want it to. Your fear that you justify by calling yourself a control freak has no impact on the result. It just makes you uncomfortable as you do your work.
Here’s something you need to remember:
If you can’t change the outcome, your stress doesn’t help.
If you can change the outcome, then stress is unnecessary.
Do what you can and train yourself to not stress about what you can’t do.
It might take some time.
But it’s time worth taking.
