Don’t pretend; do. Don’t talk; do. Don’t think; do!
An actor acts as a character who can do the thing that the actor likely in most cases cannot actually do. Their job is to act. Pretending is their “doing”. They are pretending to be the people who actually do whatever it is that the character can and does do. Everyone could have an actor playing their role.
In real life, you might put on an act for this or that reason. It should be a good one. if that's the case. No one likes a pretender.
Real life “is”. You have to “be”. Don’t act; do!
