What I never overcame is a kind of shyness.
I always felt I had to fill silences, usually by singing or whistling. It was nerves and shyness, really.
I started studying shyness in adults in 1972. Shyness operates at so many different levels. Out of that research came the Stanford shyness clinic in 1977.
Overcoming my shyness has been a lifelong struggle.
I'm very shy so I became very outgoing to protect my shyness.
