Every age has its own fear. In childhood I feared bullies and the Vietnam draft. In adulthood I feared failing at a career. I feared the death of my parents — my greatest fear to date. Please just accept that a greater fear will always arrive to replace the last fear. Then, regardless, do what you dream of doing.
P.S. In the photo recently posted of me holding the hand-lettered sign, I spelled my own name wrong. I am an idiot. At times that is a blessing.
