It's true, there is something to say about age and maturity. The more we go through in life, the more we learn, understand and become wiser. Young people tend to think they know it all, but they have so much to learn.:)
Life is a learning experience, only if you're willing to learn. You can go through life ignorant and making the same or similar mistakes over and over again... or you can learn from your mistakes and from watching others and your path will get easier the longer you live and the more you learn.
There's a saying that says " if we don't learn from our mistakes then we are doomed to repeat them" but yes life is a learning experience for those that are humble enough to be taught and life is rough and tough for those prideful enough not to be taught. Hope that makes since?
