Letting it all go
George Carlin was a comedian who played it safe. Carefully building up material and solid performances.
Until he could not anymore. He gave that all up and lost the career he had.
After that he did a radical thing: Every year, he would let go of all the material he built up. Forcing himself to start with a blank slate. To come up with completely new material.
In that courage of letting it all go, he found himself again.
