Go make a statement online and watch many come and tear it down and point out the logical flaw in your statement. How it can’t/won’t happen every time, how your statement doesn’t apply to everyone.
They are asking the wrong question.
What is possible once, is possible again. If someone says you are terrible at X (sales perhaps), then the answers are simple.
Can you make one sale? Yes.
Will you make a mistake? Yes.
Can you make one sale? Yes.
Ignore the rest. Ignore the noise. Focus on just that one. One time. One time.
