Every “successful” person had to face the possibility of failure.
Famous actors and actresses had to audition for their roles in order to get them.
Singers had to put their music out in order to be heard.
Married couples, one person had to have asked the other person out.
In all of those situations, there was a possibility of failure — no getting the role they audition for, no one listening to their music or no one finding their voice all that great, the other person saying no to you asking them out.
You can’t find success without putting yourself in a position of failure.
