Progress in life
Learning is never ending process. But there is no fun in learning the same thing again. Progress is when you learn new things.
You are bound to do mistakes. Repeating the same mistakes shows ignorance. Make newer mistakes to grow wiser.
Hardwork is inevitable to be successful. Doing the same work again and again is meant to be making you perfect too. But with age and phase of life, you need to work hard on different and better aspects. Else we grow timid.
