Why do you do what you do?

Why do different people like to do different things? Music, art, cars, computers, cooking, reading, the list goes on and on.

Personally, I love to take pictures - capturing a moment in time that will never happen again. I take pictures because it is fun for me to see what I will catch in the picture, what will the picture say, what will it mean to other people?

Why do I take pictures - because it is a creative way for me to show what I see in our world.

Now, tell me why you do what you do? Explain and give examples please.
