LIFE is: Lecture, Instructions, Faculty, Education.
So, it is like a school that only ends when you end. You don't decide who teaches you, you are given exams of various forms and you don't decide what questions you get. Your ability to pass these exams determines your progress and success.
So, live this life like you've got no school but it, learn from your mistakes and most especially others', lend what you have to benefit lives, love others like you would want them love you, and leave the rest for those who need it.
