People generally take you at face value.
If you present yourself as a confident person, most people will assume that you know what you’re doing, and will follow your lead.
Countless experiments have been done on this, and the result is always the same.
Many successful people started out by practicing in front of a mirror, pretending to be more confident than they felt.
The more they mastered the act, the more they actually began to feel more confident.
This became such a respected form of success mastery, it spawned a popular phrase.
Fake it ’til you make it.
