Write really interesting hubs about a topic you know well.
Choose a topic that is popular/in demand.
Create links to your hubs to increase traffic and awareness of your hubs.
Make sure you have all of your information set up with your google adsense account & other affiliate sites that pay you through here.
Set a goal of how many hubs you will write in a day, week, or month and stick to it. One hub a year about the mating rituals of earth worms is not going to do it.
