If you're new to IM, this isn't the question you should ask first. Instead ask yourself, "What value can I give to people?" If you can't add value to someone's life, you can't make money.
Can you do something others either can't do or don't want to do themselves? Can you entertain people by playing music or making them laugh or creating a game for them to play? Can you teach them something they don't know? Can you help solve a problem they have?
If you can't answer "Yes" to any of these questions, you need to focus on these BEFORE you ask how you can make money. Your priorities are out of order.
