I'm not a mechanic. My dad is, and he's the guy I run to whenever my car starts making a funny noise or needs some kind of diagnostic. He’s saved me countless thousands of dollars over the years.
I come to my dad because he has very specific knowledge and experience in this field. He’s a professional... people paid him for it.
Do you know who I don’t run to for answers? People who aren’t mechanics. People who have no knowledge and experience in this field.
