As a start, the first questions you might want to ask yourself:
1. What are my passions, hobbies are things I am passionate about?
2. How much time I can sacrifice on a daily basis
You are on the right platform -- hubpages! So all you have to do is to start sharing your passions with people around the world. Share your skills, knowledge or experiences with others. Help people to solve a problem etc and enjoy the fun putting it in writing.
You may also seek out a few other platforms, like webanswers.com. Here you can answer questions and get paid for it. Also, there are several survey companies online that you can signup with, however, please be careful of the ones you pick. Make sure you signup with only those who have been around for a long time and are legitimate.
Overall thou, I think hubpages is the best place to start. Good luck!
