72, this is about 3 yrs old, but probably still reinforces your point.

Also some kids don't get the breaks early on in life. Was reading a so-called elite college magazine this afternoon and read an interesting story about how a professor can help a less fortunate kid with promise.
Apparently the professor helped this student through a grueling freshman year. An African American raised by her Detroit grandparents, she dreamed of becoming a psychiatrist, motivated by her mother's mental illness.
But she wasn't prepared for fopr pre-med classes: she withdrew from her chemistry professor's class and nearly flunked out of school.
Because of her determination, the chemistry professor and mentor steered her to psychology and designed a curriculum to help her through, including scholarship money for an extra year to catch up on science courses.
He convinced her not to give up when she nearly failed medical school. Today she is a licensed psychiatrist and the professor walked her down the aisle at her wedding in 2003.
Uplifting story of the determination of a student to realize their lifetime goal and a professor who made it happen.
Also for those who care about giving a kid the benefit of the doubt, you may want to read Becoming Dr. Q. This is a true story about an illegal immigrant (who later became a citizen) who is now one of the leading brain surgeons in the country. He is a doctor and professor at Johns Hopkins and is only 43 years old. Amazing tale and it could only happen in America.
