Excellent post @cryptogee!! It seems we need these skills more and more everyday as life is seems to be more intense.
Firstly, I really appreciate your distinction here:

I believe that when people say they work better under stress. What they actually mean is that they perform well in stressful situations, this may seem like a subtle difference. In fact it is a whole lot different

Yes so very different and really clarifies the importance of how we frame our experiences in advance of, during and afterwards. We are more empowered to affect our feelings, our performance, our lives than we often realize, and it's the small moments that make all the difference.

Also I didn't know about "anchoring" and tried your technique. It feels awesome! Hopefully I'll remember to build this skill over the coming days so it becomes a reflex. Thanks for your consistently excellent posts!
