Yes, and

Richard Lewis died this week. He was part of the show Curb Your Enthusiasm, which is the most sublime improv.

Improv comedy can seem like it's all about quick wit and making people laugh, but at its core, it's about collaboration, creativity, and adaptability.

The foundational principle of improv is "Yes, And".

"Yes, And" means accepting what someone offers you (the "Yes") and then building upon it (the "And").

Curb Your Enthusiasm is created completely unscripted. Cheryl Hines has described that she often goes on the show without knowing at all what they are doing that day. At most, they start with a paragraph description of a scene. The rest is all done ad lib.  

Here is a short clip describing how they do it. It blows my mind.  It gives me pause about overthinking and to do lists.
