Need to make money? Sell yourself!
Most people find this hard to believe but making money online (I'm using "online" because that's what I'm best at) can start with the thing you would think of last.
When people first think about making money online, whether it be for extra income or something more, they rack their brains for answers on what to sell when the best place to start is to ask yourself "what do I enjoy doing?" "what am I good at?" "what do I believe in?". Selling something that you know about, are good about and/or truly believe in is the easiest selling you'll ever have to do. In fact, it won't feel like selling at all, it'll come naturally.
The web is a wonderful place that lets crappy writers like me make money with their ideas! Publishing on the web compared to printed format it much easier.
I'll take me as an example. What do I like and are good at? Online business, drop shipping, the wholesale industry, web technologies, web hosting, domain names, chess, keeping in shape. This is just a quick list of things I could write for hours on end without having to do any research or thinking.
EVERYONE has things they can write about and EVERYONE has things to contribute to others who have the same interest. What you take for granted, as what every knows isn't so! Just because you know of something, doesn't mean the rest of the world does. Everyone has a unique perspective on things and each perspective is interesting and worth reading.
Start by making a simple list like I did. Cooking, raising your kids, housekeeping, cricketing, metal detecting, bowling... Whatever! This is list of things you can write on, turn into an ebook and even a printed format (see post below about LULU.com allowing you to publish a printed book super-easily) and make money with!
I often buy ebooks, reports, lists and other digital media from authors in my line of work... alot of the time, I know 95% of the things their writing about, but I always find a unique angle, trick and a different perspective which makes it worth buying.
You have something to sell. Write about something that comes naturally to you, add a bit of researched data if you want, proof-read it a few times and turn it into a digital ebook.
The biggest mistake you can do is to think that nobody will want to read what you have to say and avoid doing this.
I promise you. Someone WANTS to hear what you have to say about ant farms or raising turkeys :)
