Why is it that when you speak to someone older it sounds foreign to them? I'm applying this question to giving advice. Age doesn't make you dumber nor smarter. It really shouldn't define you at all. It should only be a systematical way to keep track of your life. That is what it is genuinely designed for anyways.
Yet, society seems to use it as a way to define your experiences. Trust that there are pretty intelligent teenagers who have had it rough and had to grow up faster than others. In my opinion, that is karma that has been passed on from a previous life. It honestly makes you ignorant and immature to dismiss good advice because it came from someone who is younger than you. Everyone has different experiences.
When I tell people that they can learn from a small child they often laugh. I, then give them an example of a time my niece who was five at the time. My great grandmother had passed suddenly and I was really down. My niece looked to me and said, "Auntie don't be stressed. You have to take things one day at a time." I was stunned from hearing those words of wisdom from someone who hasn't even been here that long.
I was equally impressed by how she knew the word "stressed" and applied it perfectly. It really opened my eyes and from that day on I think of her words and they truly are taken to heart. Once I tell people that story then they start to realize that wisdom comes in different packages. That is after a small chuckle. This world is a bubble of experiences and an obesity of wisdom.
There is no reason that we should be lost. If you are open to receiving and leave it at that then you'll be good. Sometimes I have been blessed with the ability to offer guidance to those who are twice my age. I believe it is because I have an old soul. Our physical may be in this lifetime, but our soul is of many lifetimes. Allow it to guide you to wisdom.
