Being successful at something doesn't automatically make you an expert but becoming an expert does bring success. While success can sometimes come quickly, reaching expert level takes time, willingness to learn, and moving through failures.
When we have a passion to do something, we should lean into that passion and ignore the "haters" who don't understand our dreams. Learn everything we can about that area (both what works and what doesn't) so that we become our passion. That's how we become an expert at something.
