Practice Naked Confidence
Here’s something I’ve done over the years that’s effective for building confidence and phase frame (and generally not giving a shit about the little things).
Imagine a scenario where someone random walks in on you naked. Do you feel embarrassed? Do you flail wildly to cover up? Or do you calmly look into their eyes and say with a smile on your face “hey, how’s it going?” as if you don’t have a care in the world?
Mentally practice putting yourself in socially awkward situations, and mapping out a best case, confident, unphased response. This will help train your mind to be more cool and collected when you encounter life’s big surprises.
