I am very interested in philosophy and took college courses in it. it is just so fascinating and teaches us a lot about the world. 
Even the fact you are in school is Philosophy which translates to love of wisdom.
I think there is so much behind everyday things and everyday decisions. Understanding these things can help you function in the world. 
Its the very philosophical method to question and discuss these thought.
If more people thought about things like that, the world would be different. People don't think about their motivations or why they do things. Philosophy can teach you about the world and yourself. 
the classic question is, Is it possible to know anything, and to then even prove it?
