You need some insecurity if you're an actor. It keeps the pot boiling. I haven't yet started to think about retiring. I was shocked when I heard about Paul Newman retiring at age 82. Most actors just fade away like old soldiers. ↗
You should never meet your heroes. Paul Newman... I was so excited about meeting him, but he turned up in shell suit bottoms, slippers, and a jumper. He was just so worn out and old, he wanted to go home. ↗
