“I refuse to join any club that would have me as a member”

Simplified Meaning:

When someone says they wouldn’t join a club that wants them as a member, it means they have a certain level of self-doubt or believe that if a group is willing to accept them, that group might not be good enough. Imagine a popular kid in school who gets invited to join a group of friends who aren't very active or interesting. He might think that if this group finds him cool enough to join, they must not be as popular or fun as he wants. From another angle, it’s like a job that hires people very easily; you might wonder if it’s a really good job or a company with high standards. So, if you think highly of yourself, advice from this quote would be to seek out groups or opportunities that challenge you and have high standards, instead of settling for something that doesn’t help you grow or improve. This can help you aim higher and achieve more in your personal and professional life.
