For many of us, writing is a good way to earn money. For some people, it's a good way to express their creative thoughts. Their motivations for writing may vary from person to person.
For me, I write because there are so many things that I want to buy (ex. computer upgrades, books, virtual video game hats, etc.) but we simply don't have the financial capability to do so. Whenever I write, the thought of gaining the things that I want motivates me.
How about you? Why do you write? What motivates you to write?
