Everyone has some hobbies. For example, collecting hockey cards, playing video games, computer games, watching favorite TV shows, wrestling, playing with dolls, ect. 

However one should understand that these things have big messages behind. And from these hobbies we lose only. We develop a habit to collect as many as we can never ending, and then you need to know about it.

Satan keeps you busy to waste your learning time towards useless hobbies. And your brain will only be occupied with things that have no learning. 

Your age group is the most important age. Because your brain is developing, if you are going after music, dance, movies, and all other useless things. Those things have no end, it is just like sinking in quicksand without knowing how deep it is. 

You should put your time towards learning about your future. You always have to make sure you have value for your time. And these things are learned towards praying five times a day. 

Your hobbies should be learning more and more about the Prophet's stories, and stories from the Qur'an. And to learn the laws in the Qur'an. If you learn the entire Qur'an with understanding of its translation, then anytime you have a difficulty, you will know what to do, by what the Quran or what Prophet Muhammed says. 

So you don't have to depend on your mother or father, or to learn from your friend or brother or sister. Because you can be misguided by any human being, who's knowledge is limited. 

But if your hobbies are to collect the examples of the Prophet Muhammed, and the hardships they went through during there lifetimes. Every Muslim should know this regardless where in the world they live in, or how rich or poor they may be. 

So you can set yourself as an example, what price the companions of the Prophet Muhammed, paid because they were the true Muslims. 

We always should make a quiz for fun about Islam. And make sure we become the best Muslims amongst your friend. Always completion for who can be the best Muslim, always ask each other, how much Qur'an do you know, or what to you know about the Prophet (SAW) and his sacrifice to Islam. Then you can make yourself a good Muslim, and you friends also, by doing good deeds.
