Reading Journal

I am not reading this book but i like this quote from Chicken Soup for the Girls Soul. the quote says "I have always grown from my problems and challenges, from the things that don't work out. That's when I really learned" by Carol Burnett. I like this quote because I know that we all have problems or challenges and we all try to work through them. But in order to learn from them we have to make the mistake. But why do we have to make the mistake just to learn form them? why can't it be easier, like something we just learn? that will always keep my mind going and maybe one day I will find the answer.
