Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Though this may not be an ideal situation, taking in a long-term roommate can drastically reduce your housing payments. The best roommates are those who you already know to be relatively friendly and like to maintain their current living space in an orderly fashion. If you do not know of anyone who fits the bill, you can usually find someone either on Craigslist, or a few other “roommates wanted” websites.
There is a market for nearly everything collectible on the world’s largest online marketplace. You can often find these figurines or oddities at garage sales or auctions for a very low price, then proceed to sell them on eBay for a tidy profit. Whole sets will usually command more than individual pieces for an online listing, but you can usually get a full set of anything cheaper than these individual pieces at auctions/garage sales.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
