I think age matters for success. It is not possible to see a 25 year old man in a CEO position (only exception to this is when his father owns the business). Even to make money, age is often seen as a significant factor. Can a 50 years old man work as hard as a 30 years old man? While some individuals achieve financial success in their later years, a lot of successful people have found success before they are too old. Even when someone becomes very successful in old age, that is the result of hard work in the early age.
