We get advices from various ages of people. It is good to get advices from friends at your own age, but it would be even better if you get advices from older people. It's because they have broader views, and they are more mature.
To begin with, people at older ages have already undergone through the experience that you are confronting right now. Therefore, from their own experience, it's easier to advice in many ways. To illustrate, I have two brothers. They are both currently attending university. When my oldest brother had to go to college, he prepared a lot of things with his friends at his own age. However, his friends didn't have much knowledge about college, so he had hard time applying for his college and getting in. On the other hand, my older brother, whom got helped by my oldest brother, had easy time preparing for college. My oldest brother helped my older brother with his own experience.
In addition, people at older ages are usually more mature. They are more wise to think of the surrounded environments. Therefore, it's easier for them to advice younger guys with their mental maturity. For example, my father has a friend who opened a restaurant in Canada at the age of 28. His friend was still so young and lacked knowledge about business. However, he had a clever marketting idea, and he was quite sure that the idea was going to work. However, my father with the age of 40 knew that the marketting item was clever, but wouldn't work. My father told his friend that there are lots of things to consider before even opening the business. My father told his friend to pay attention to the place where the restaurant is going to be made, and check if any other person has the same marketting idea. Afterwards, his friend suceeded with his business and thanked my father.
In conclusion, it's more wise to get advices by people of older ages than people of your own age, because older people have broader views, and they are more mature than younger people.
