Dale Earnhardt Jr. appeared on CBS This Morning on Wednesday and read a letter he wrote to himself, reflecting on his relationship with his father and his rise to stardom as NASCAR’s most popular driver.

Earnhardt Jr., who will begin his quest for the Sprint Cup championship this weekend at Chicagoland Speedway, was featured in CBS’ “Note To Self” segment in which he wrote a letter to the 16-year-old version of himself.

“To a 16-year-old Dale Jr.,” the segment begins as Earnhardt reads his letter.

“Writing this letter to you is going to force me to think pretty deeply about my life, and you know thinking deeply was never one of your favorite activities. You always did and always will shoot for the C on your report card. Anything more than that is always going to be a surprise to you.”
