What do you want to do with your life? What's your dream? Why do you want that?

For me I'd like to drag people from places that they think they can't get out off.Im very selfish cause you might say but they never asked for your help,but I think that people need people so if we don't do something who's gonna do it? I guess it's because once I saw a person who needed help but no one, including myself, had the courage to step out and help,but when time passed and I saw that someone fell on the ground and how 3 people rushed to help the man up as I asked if he was okay while my friend picked up he's cigarettes box.
It's a simple but a complex question: what do you want to do that satisfies you,and only you and you don't expect any reward for it, something that is purely based on your own personal fulfilment.
