Make sure, when you see any bad thing, you don't adopt. And any good thing, and manners, and to nicely talk, with people who are younger or older than you. And your parents. If you respect people, regardless how old they are, then they won't bother you, and you will be respected.

If you start to think, about how Allah has made this world, and how he is holding the stars, and how the food, that I eat makes me grow, and I digest it. How precisely I am growing, all my fingers, hands, and all the parts of my body, are growing accurately. And what makes me think, and where do I store my thoughts. And I call back my thoughts and use them in life.

If you start thinking about these aspects, you already start to go to the right path. All intelligent people think and show they are grown people, to act right, to do right, and think right.

Regardless of your age, never show that you are irresponsible, careless, or poor thinking person. Anything useless, we don't gain from it but we lose a lot. And sometimes we have to pay the price. Like an accident can loose any part of the body, or to break something at home, it could show your carelessness.

These things looks like they are easy to say, but if one follows it, you are a grown person.

But how can I become an intelligent person?

All of the smart people, plan for the future. And they do not build there house in a day. Sometimes it could take years to make a palace, the same thing, our life is very short, you can see, some of the kids die before they become youth. Because the angel of death never asks someone's age, or he will never say that you did not grow yet, I will come back again.

Be smart, not a looser, never follow a person, no matter how old they are, if they don't follow Allah, and they do not practice Islam, then that means they worship Satan.

So be intelligent, and prepare yourself, to make a big house in the hereafter, and always seek help from Allah. And follow the examples of the Prophet (SAW) and do not look at anything else.

Your key to success is the Quran. And the examples of the Prophet (SAW).

Just do what the Prophet and his companions did, read there stories, and adopt it so you become like them.

Then you would be smarter, then any grown person. Regardless of age, keep reading this article again and again, and don't let it go, this is the key to grow, in the shortest and fastest way.
