Does everyone have to be some Nobel laureate doctor President who cured cancer to be successful? Certainly not. Some people can, and will, and have, gone their whole lives without doing anything that we might consider "successful". But they still contribute to society. They help the gears turn. In turn, society offers them little pleasures, which keep them occupied. Some people are not destined for greatness. Some are not destined for even mediocrity. But with the right systems in place (we're certainly a ways away from this being true, but baby steps here), every single human being can find purpose, contribute something of value to the sum of humanity, and enjoy their lives on Earth.
"Success". What is success?
