What is the worst advice you have gotten?

This can be about any subject and can be funny or serious.What is the worst advice you have gotten?
In Grade school I was a late bloomer. I didn't understand most of what was being taught. No one taught me study habits. Overwhelmed by the homework and reading, I didn't do it. I passed three grades on condition that I go to Summer school. In my first year in High School, my dad sent me to one of the toughest prep schools in the country. I flunked out. I barely made it through High School and had to get a tutor to make it through College.What is the worst advice you have gotten?
