I am not going to give you names of websites or affiliate links, or point you to place which most likely are scams (not saying everything is a scam). I'm instead going to focus on how you can literally discover what is the right thing for you to do and how to make money.
If you truly want to make more than just spare change, read through the answer below.
Work for Someone From Home
Working from home does not necessarily mean, freelancing. This is one of the biggest misconceptions. One can work for a company from home. There are so many companies that are okay with the concept of remote workers. Doesn't matter if you're in the US or across the world. Companies will hire anyone whom they feel are an excellent resource.
Jason Fried, Partner at 37Signals (the makers of BaseCamp), has an excellent video on this, working remotely:
To make money, either by working full-time, part-time or freelancing from home, requires that you are passionate about something. Passion trumps everything and all obstacles.
Passion is just one side of the coin, the other side is building-value. Whether you build value in your skills-set, or the content, effort, etc. you put on the web, you must build-value for to make money.
As with anything else, there needs to be a demand for something. This something is what you have to be passionate about. If you have something that has a demand, and you build value, you can bet your bottom dollar, that someone will be willing to pay you for your time or effort (contribution).
Work finds talent. Talent finds work.
Find Your Micro-Niche
Finding your niche is what it is all about. Your talent is your niche. If you're good in article writing, thats a starting point. What type of articles you are good at writing, is your micro-niche. If you like photography, what type of photography do you like? Can you do stock photography? Are you good with portraits? You may love photography, but perhaps you're even better in doing post-production work on them. That just may be your micro-niche.
You have to focus. You must learn to say no, to things outside your domain of expertise. If you are a subject-matter expert in a particular area, say no to work outside this area. Taking working outside this area is the classical case of losing focus and being distracted.
Finding your niche and micro-niche is easier said than done. Ask your family, what they think you are good at? Ask your friends, your colleagues, people who have interacted with you. Make a list of things you are passionate about and then slowly shorten the list, with realistic goals like:
Many times, people already know what they are passionate about. What your micro-niche is. Now you just need to get started.
I personally know so many qualified people, folks with masters degrees and double-masters, etc. yet they are wasting their life, day-dreaming, promising themselves they will do it one day. They never do.
There is a difference between a wish and actually-doing-it. Only you can make a difference. No one else can. If you truly want to make money on the Internet (whether working for someone, or doing something of your own), you have to get up and do something about it.
As I said, passion will trump all hurdles. If you genuinely love what you do, then do it. Become the best at it, and work will find a way to you.
There are 100,000s of people perhaps who are trying to compete for work everyday...
All these questions are easy to ask, but they don't have an easy answer. If you're content with making a few cents doing repetitive / mundane tasks, Amazon Mechanical Turk might be your thing. If you have the ability to deliver quality work fast, not spend too much time on it, for a specific talent, Fiverrmight just have a gig for you.
Don't Give Up. Persistence is the Key
"A river cuts through a rock not because of its power, but because of its persistence."
You may not get business on day 1. Not even on day 2, but if that is going to be your criteria of making money, from the word go then I have bad news to tell. Its never easy.
You will get better with each try! I can guarantee you that. I know freelancers who had sent over 200+ proposals (bids) to potential clients, before they got their first break.
I know of a blogger who blogged for months, before he found his first paying gig and now lives comfortably of it.
I know a logo designer who refused to compete with the lower pricing in various marketplaces and held steadfast to her pricing menu. She did not get business for a good year. Today, she cannot keep pace with work.
Some just have sheer bad luck. They keep changing their plans, just when business would have steered their way. They keep doing this way too often and then get frustrated and quit all together.
Get help. Find a mentor. When in doubt - Ask away!
Sometimes complacency will not make you think straight. Its good to get an external view on such matters.
