Funny- we have a micro-sensitivity to ourselves; no wonder we are so self-absorbed!
Think about all that listening to our own voices in headphones, with every nuance amplified into our own ears and every emotion bigged up giant-size on a billboard inside our vain brains.
In the studio, even our breathing has a potential commercial significance. We are More Important Breathers than people who don't go into recording studios. Our breathing isn't just for keeping ourselves alive- it's for Being Significant.
As for our singing- we can be genuine until we learn how to be artificial, and then we spend the rest of our days striving to sound genuine again!
